Best Running Jackets of 2024

Having the right jacket is key whether you need extra warmth during a cold winter run, shielding from the wind on a high ridgeline traverse, or protection from the rain. The best running jacket will keep your core temperature warm without causing overheating, breathe well to prevent sweat buildup, and can make cold- or foul-weather runs much safer and more comfortable.

The iRunFar team has been running in jackets of all types in nearly every climate imaginable. From using a light windbreaker to ward off a morning chill to having insulated jackets to carry on cold romps through high peaks, we tested some of the best running jackets available from the California coast and hills to Colorado’s high San Juan mountains. We test in the rainy and damp U.S. Pacific Northwest, sandstone canyons of central and southern Utah to determine which jackets perform best under various conditions. Some of the jackets in this guide have been go-to favorites for our team members for years, with countless miles of use in adverse conditions, and others are new to the testing pool. We evaluated various jackets based on their waterproofness, comfort, style, breathability, and durability.

When it comes to a light jacket that can do everything from keeping you warm on a chilly morning run to protecting you from whipping wind high on a mountain ridgeline, we turned to the Patagonia Houdini Jacket. When we needed an ultralight rain jacket, we turned to the Inov8 Raceshell HZ, and when things got really cold, we went for the insulation of The North Face Thermoball Eco Hoodie 2.0.

Best Windbreaker: Patagonia Houdini Jacket ($109)

Pros:

• Ultralight
• Good value

Cons:

• Noisy when in motion

A long-time favorite amongst ultrarunners, the Patagonia Houdini Jacket has earned a reputation for being an ultralight jacket option that provides a lot of protection in a small package. If you look around at an ultra’s early morning start line, you will likely see many people wearing this jacket, and there’s a reason it’s found itself at the top of our Best Windbreaker Jackets guide. Many of the weight savings come from this jacket having very few extra bells and whistles. It has a single front pocket, just big enough to carry a few small items like a credit card or gel, and elastic on the cuffs to keep heat sealed in and the sleeves in place.

One of the much-appreciated features of this jacket is the large adjustable hood. It cinches down to fit snugly around a bare head, but it is also large enough to fit over nearly any type of hat, including climbing or cycling helmets.

This jacket reflects Patagonia’s commitment to environmentally friendly production practices. It features 100% recycled nylon ripstop, and the DWR coating is PFAS-free, a much healthier option environmentally than coatings that contain perfluoro compounds.

This jacket stuffs into its own chest pocket and is small and light enough to always keep it in your bag as a just-in-case layer.

Best Windbreaker — Runner-Up: Montbell Tachyon Hooded Jacket ($139)

Pros:

• Incredibly lightweight and packable
• Adjustable hood

Cons:

• Shiny material may not suit all tastes

When all you need is a light windbreaker to ward off the chill of a cool morning or one that you can toss in your pack or pocket in case you get cold while out on the trail, the lightweight Montbell Tachyon Hooded Jacket is a great option.

Weighing a mere 72 grams and compressing to nearly nothing, this jacket is made of thin seven-denier fabric but is still durable enough to withstand use in the mountains. While shiny, the fabric doesn’t make much noise during movement. These features make it stand out next to other windbreakers, earning it a spot in our Best Windbreaker Jackets guide. Our mountain running specialists also include it in our Best Mountain Running Gear guide.

Surprisingly, even though this jacket weighs next to nothing, it has some extra features, including two outside pockets for hands and an inner pocket for securing small items. The hood has pull tabs to tighten it for a secure fit, and elastic around the wrists keeps the sleeves down. The underarms have small vents to help with body temperature regulation. A DWR coating provides water resistance, but this jacket doesn’t work as a full rain jacket.

Best Rain Jacket: Patagonia Storm Racer Jacket ($299)

Pros:

• Excellent waterproofing
• Good fit for running
• Environmentally conscious construction

Cons:

• Lacks breathability
• Expensive

We were big fans of Patagonia’s mountain-running rain jackets, and the brand’s newest version of the Patagonia Storm Racer Jacket doesn’t disappoint. For a few years, Patagonia put a side zipper on this jacket to provide easy access to a running pack, but we’re glad they’ve returned to the single center zipper.

We also love this jacket’s slim fit, which avoids the boxy feel many rain jackets have. This jacket also has semi-elastic wrist cuffs, a hood with elastic around the edge that does an excellent job of wrapping around your head, and a drawstring at the hem to help seal the jacket around your waist. For storage, the Storm Racer packs into its own pocket. It takes some work to get it back in, but it makes for a compact package you can easily carry in your hand, running vest, or belt.

And since it’s Patagonia, you know a concerted effort has gone into making this product as planet-friendly as possible. Patagonia employs its H2No waterproof technology in the material, which features 100% recycled ripstop polyester, a comfortable tricot backer, and a PFAS-free DWR coating. This jacket provides a reasonable amount of warmth and excels in cold and wet conditions. You’ll probably want to choose something lighter if you’re running in a warm rain. You can explore other options in our Best Running Rain Jackets guide.

Best Ultralight Rain Jacket: Inov8 Raceshell HZ ($140)

Pros:

• Very lightweight
• It fits over a pack

Cons:

• Fragile-feeling zipper
• Has the appearance of wearing a garbage bag

If you’re searching for one of the lightest rain jackets on the market, look no further than the Inov8 Raceshell HZ. We’ve consistently included this anorak-style jacket in our Best Running Rain Jackets guide as one that weighs next to nothing and meets most races’ mandatory gear list requirements. Its 2.5-layer construction and fully taped seams inside a polyester outer with a polyurethane waterproof membrane provide complete waterproof protection. The half zip saves weight while decreasing the chance of water seeping in.

While this jacket has the stylistic appearance of a plastic bag, the lightweight material is quiet when running. On the plus side, the translucent material allows a race number worn underneath it to show through.

This jacket sacrifices any extra features to keep the weight as low as possible while still being waterproof. There’s no adjustability in the hood, cuffs, or hem, so there’s minimal room to dial in the fit. The wider profile of the jacket allows it to fit over a small running pack and makes it easier to take on and off while on the move. While it seems Inov8 designed this jacket for specific racing needs, we also appreciate the features that make it more efficient during regular runs. The zipper is tiny and feels fairly fragile and stiff. During testing, we were always careful zipping and unzipping it out of fear of damaging the zipper or the material around it. That said, the zipper continues to work without issue after extensive use.

Best Hybrid Insulated Running Jacket: Patagonia Nano-Air Light Hybrid Hoody ($299)

Pros:

• Highly breathable
• Lightweight
• Strategically placed insulation

Cons:

• Expensive

When it comes to running in cold weather, you can trust the Patagonia Nano-Air Light Hybrid Hoody to keep you warm and comfortable. This partially insulated jacket is perfect for higher-effort runs when it’s cold outside or more mellow jogs in merely chilly weather.

The synthetic insulation, strategically placed throughout the jacket, will keep you warm even if it gets a little damp from sweat, and the polyester shell is highly breathable. Patagonia’s R1 Knit paneling makes up the non-insulated sides and back of the jacket. This highly breathable and quick-drying fabric makes it more comfortable to wear a pack during cold conditions, as it keeps your back from getting too sweaty underneath it. The jacket’s hood is easy to get on and off, and two zippered pockets can hold small items or provide extra warmth for your hands. Weighing just 11.8 ounces (335 grams), this jacket is light enough to stuff in a pack when you’re not using it.

We’ve been testing this jacket for about a year and have logged hundreds of miles with it in tow. It continues to be our go-to pick for cold conditions. The well-placed insulation, breathability, and stretch make it an excellent option for high-output winter activities like running. We really love how the insulation helps keep the core warm — especially on windy days — and the back fleece panel wicks moisture while also helping offload excess heat. It’s a highly thought-out and well-designed piece of incredibly versatile gear. This jacket is featured in our Best Insulated Jackets for Running guide and our Best Cold Weather Running Gear and Best Winter Running Jackets guides.

And regarding environmental considerations, Patagonia has always been a leader in the outdoor industry. Patagonia constructs this jacket in a Fair Trade Certified factory, and the company is part of the 1% for the Planet program, which donates part of its profits to organizations working to preserve the environment. The shell of this jacket is made of 100%-recycled polyester and has a perfluoride compound (PFAS)-free durable water repellent (DWR) coating, a more environmentally friendly option than previous options for adding water resistance to a jacket. The insulation also features 93%-recycled polyester.

Best Fully Insulated Jacket: The North Face Thermoball Eco Hoodie 2.0 ($270)

Pros:

• Lightweight and packable
• Works well for fastpacking and backpacking

Cons:

• A slim cut is not ideal for all
• Not necessarily a running-focused jacket

A long-time favorite jacket of the iRunFar team, The North Face Thermoball Eco Hoodie 2.0 is a lightweight, packable, and warm-for-its-weight insulated jacket. It’s made of 100% recycled materials and has a unique quilted pattern not seen in many other jackets. To make this jacket as environmentally friendly as possible, The North Face used a PFAS-free DWR finish for water repellency if you get caught out in a rain shower. Luckily, the synthetic insulation is warm even when wet.

Two zip hand pockets are great for warming cold hands and storing small items. The jacket also stuffs into these pockets for easy storage in a pack when not in use. A secure chest pocket is an excellent spot for keys, a gel, or any other small item.

This women’s version of this jacket is cut relatively slim compared to other similar jackets, but it comes in plus sizing options. iRunFar’s Meghan Hicks opted for this jacket for many shoulder-season runs that had the potential to turn cold and also as her just-in-case layer for long mountain outings.

We also include this jacket in our Best Insulated Jackets for Running and Best Winter Running Jackets guides.

Best Insulated Jacket for Fastpacking: Mountain Hardwear Ghost Whisperer/2 Hoody ($360)

Pros:

• Very light for its warmth
• Compressible

Cons:

• Expensive

Including a down jacket like the Mountain Hardwear Ghost Whisperer/2 Hoody in a running jacket guide might seem like a bold move, but we think there are as many different types of “running” as there are jackets. When it comes to fastpacking trips and all-day runs in the mountains, starting and finishing in cold temperatures is a distinct possibility, and this is a great lightweight option.

Down is lighter and compresses smaller than synthetic insulation, and at 7.8 ounces, this jacket can fit into a running vest for the days you want the extra warmth. While you have to be careful not to sweat in it or let it get rained on, the warmth-to-weight ratio of this jacket makes it worth taking the extra precautions. It’s been the go-to option for fastpacking trips for multiple members of the iRunFar team.

The recycled 10-denier ripstop nylon outer is durable, and a DWR finish provides water resistance. This jacket is designed for performance and employs 800-fill down insulation that is Responsible Down Standard (RDS)-certified. Two hand pockets are great for warmth, and the jacket packs into them for easy storage. Since down is more compressible than synthetic insulation, this jacket packs down smaller than the other insulated jackets in this guide.

Elastic on the hood and cuffs keep the jacket in place and increase its warmth, and the final baffles on each of the arms, a traditionally sweaty area, are filled with synthetic insulation to combat heat loss due to moisture, a thoughtful detail. Even though it’s down insulation, we still include this jacket in our Best Insulated Jackets for Running guide as our top pick for fastpacking adventures.

Weight: 7.8 ounces (221 grams) | Shell material: 10-denier ripstop nylon with DWR finish | Insulation material: 800-fill RDS-certified down insulation Certified by Control Union | Waterproofness: Water-resistant

Best Reflective Running Jacket: L.L.Bean Bean Bright Multisport Jacket ($99)

Pros:

• Great visibility
• Good pockets

Cons:

• Very bright during the daylight
• Longer than normal sleeves

When visibility is a top priority during dark runs in cooler and cold weather, nothing is quite as bright as the L.L.Bean Bright Multisport Jacket. This jacket is a lot, but when you want to maximize the chances that a passing car will see you, a lot is what you want. Named appropriately, this jacket doesn’t just use reflective hits; the whole thing is just plain bright. For this reason, it was the top choice for a jacket in the iRunFar best reflective running gear guide. In addition to its hi-viz color, which makes it an excellent option for running on roads in the daylight, it also has 14 points of reflectivity for even more visibility at night.

The 50-denier polyester is quite warm and creates a comfortable microclimate for you when it’s cold out. A back vent releases excess heat, though our tester found they still got hot running in this jacket when it wasn’t straight-up cold out. The DWR coating allows it to shed light precipitation as well. The drawcord on the hem provides adjustability, and two front and one rear pocket provide plenty of storage. There are also two interior pockets, one big enough to hold a phone and secured with Velcro. These features, in addition to the reflectivity, have earned this jacket a spot in our Best Windbreaker Jackets guide as well.

Our only gripe with this jacket is that the sleeves — designed for cycling — are slightly longer than we’d like.

Best Budget Running Jacket: Montbell Wind Blast Hooded Jacket ($95)

Pros:

• Affordable
• Warm

Cons:

• Less compressible than other options

Not everyone wants an expensive top-of-the-line jacket to run in the cold, and the Montbell Wind Blast Hooded Jacket is an excellent option for those looking for something simple yet functional. While the price is lower, this jacket doesn’t lack the features of many more expensive jackets in this guide. Three pockets provide plenty of storage, and a drawstring adjusts the hem.

The 40-denier nylon shell with a DWR coating is durable and warm and compresses to a reasonable size. A little heavier than some of the other non-insulated jackets in this guide, it’s still an excellent option for most situations. Vents on the underarms release heat and help with temperature control. The hood fits easily over a head, and two adjustment points make it easy to cinch it down in bad weather.

The price and functionality of this jacket have landed it in our Best Windbreaker Jackets guide, too.

How to Choose a Running Jacket

There are a lot of factors to consider when deciding between the various running jackets available. What sets the best running jackets apart from the rest? In addition to a jacket’s ability to protect you from the elements, be it cold, wind, rain, or snow, it’s also important to consider a jacket’s fit, weight, and durability. If you just want a single jacket, or maybe two, to cover all your running needs, you’ll also want to consider the versatility of the various options. Consider the Patagonia Storm Racer Jacket if you’re looking for a solid rain jacket that can handle wet conditions. If you just want wind protection or a bit of extra warmth, something simple and light like the Montbell Tachyon Hooded Jacket will do the trick. And if you’re looking to stay warm in cold conditions, we recommend a hybrid insulated jacket like the Patagonia Nano-Air Light Hybrid Hoody.

Fit

You should consider multiple personal factors when determining a jacket’s fit. Are you planning on wearing multiple layers underneath it? Do you want it to fit over a pack? Do you prefer a slimmer fit or one that gives you a little more space?

Many runners prefer a slimmer fit, like that provided by The North Face Thermoball Eco Hoodie 2.0, that keeps their silhouette as streamlined as possible. Slimmer-fit jackets are great if you’re only wearing a single layer underneath. A larger jacket allows for a little more versatility when wearing layers underneath, but it may also flap in the wind if it’s too large. When venturing into the high mountains on all-day runs or multi-day fastpacks, we preferred a jacket that gave us maximum freedom for layering for warmth underneath. Some jackets, like the Inov8 Raceshell HZ, are designed a little bit looser so that you can fit a pack underneath.

Many jackets come in both men’s and women’s versions, with variations in length and shoulder and hip width. Some have different pocket setups as well. Choose a jacket that fits your specific body well, regardless of what a label says.

As always, the best way to test a jacket’s fit is to head to a store to try it on. If this isn’t possible, check out a company’s sizing chart before purchasing.

Packability

For many trail runners, a jacket isn’t going to stay on for the entirety of a run. You may want to start a chilly morning run with a windbreaker, like the lightweight Patagonia Houdini Jacket, and then stash it as the day warms up, or you may want to put on a layer as you gain elevation in the mountains and the wind picks up. Or you may need a rain jacket, such as the Patagonia Storm Racer Jacket, that comes out during afternoon monsoon storms or a lightweight insulated jacket, like The North Face Thermoball Eco Hoodie 2.0, that you carry as a just-in-case option for shoulder-season mountain runs where temperatures have the potential to plummet and create a dangerous situation if something goes wrong.

Like any piece of gear, a jacket won’t do you any good if you deem it too bulky or heavy to carry. Most of the jackets in this guide will fit comfortably in a running pack, and some will nearly disappear with their small volume. Check out our Best Hydration Packs for Running guide if you’re looking for a running pack that can carry a jacket.

The volume of a jacket tends to increase with the level of protection it provides. An ultralight windbreaker like the Montbell Tachyon Hooded Jacket can weigh as little as 2.5 ounces and scrunch up to nothing in the bottom of a pack or even a pocket, while a rain jacket will take up more space. An insulated jacket will be even more bulky, and an insulated jacket that protects from moisture will be even larger.

Weight

Jacket weights can vary widely based on the type of protection they provide and the quality of the materials. As runners, we tend to prioritize lightweight products that allow us to move efficiently and quickly, and jackets are no exception.

Generally, you don’t want to save weight by skimping on safety, and jackets fall into the category of safety. When looking at different jackets, it’s important to consider the level of protection you’ll need. Do you just need something to keep the wind off on a day with no chance of precipitation? Will it be cold enough to warrant taking an insulated jacket along? Are you facing a full day of racing in a downpour? If you know you’ll be out in the rain all day, you’ll want to carry a fully waterproof jacket like the Patagonia Storm Racer Jacket to stay dry. Safety should always be a consideration when choosing a jacket, as a product that doesn’t protect you from the elements just ends up as wasted weight anyhow and can lead to a dangerous situation.

Material

When simplified into major categories, jackets will prevent heat loss from wind, keep your body dry from incoming precipitation, or trap as much heat next to your body as possible to keep you warm. Some types of jackets can do all three simultaneously. Jackets need to do all this while breathing well enough to keep sweat from building up on any layers you wear.

Wind jackets generally feature ripstop nylon. This lightweight material is great for blocking the wind while allowing moisture to evaporate. Most windbreakers are coated with a DWR coating to make them water resistant and able to provide some protection from light rains. The Patagonia Houdini Jacket is one of the most lightweight jackets available, offering good wind protection. Many companies, including Patagonia and The North Face, are moving toward using PFAS-free DWR coatings. While the perfluorinated compounds used in the original coatings are incredibly hydrophobic and excellent at keeping water from soaking through, their manufacturing leads to many toxic byproducts. New DWR coatings use wax, silicone, or plant-based coatings instead.

Rain jackets generally are classified into those that have one, two, 2.5, or three layers. The material in rain jackets is rated for a certain level of waterproofness, measured as the hydrostatic head. The higher this rating, the more waterproof a jacket is. The lowest hydrostatic head measurement of a reasonable rain jacket is 10,000 millimeters. You can read more about the specifics of these different types of measurements and jackets in our Best Running Rain Jackets guide. A three-layer jacket like the Patagonia Storm Racer Jacket will provide the highest level of protection but at the expense of a higher weight.

Insulated jackets are generally only used during the coldest of running conditions. While down insulation is lighter than synthetic insulation, it also ceases to provide warmth when wet and can easily be sweat through if you’re not careful. Most insulated running jackets use synthetic insulation to combat this problem, as synthetic insulation doesn’t compress when wet the same way that down feathers do. Insulated jackets, regardless of the type of insulation used, are designed to trap as much heat next to your body as possible by creating air pockets between gaps in the insulation material. These air gaps prevent heat transfer between your body and the outside air. Jackets like the Patagonia Nano-Air Light Hybrid Hoody use recycled synthetic insulation to be as environmentally friendly as possible.

Mobility

A well-fitting running jacket will give you a full range of motion in your arms and torso. A running jacket should allow you to raise your arms above your head comfortably without the jacket riding up on your torso and exposing your stomach and lower back. The sleeves should also be long enough to cover your wrists through an arm swing’s full range of motion. The Patagonia Storm Racer Jacket has long sleeves and cuffs cut to provide extra protection on the back of the hands, an excellent detail. The L.L.Bean Bright Multisport Jacket, which is also designed for bikes, has particularly long sleeves.

Insulation Type

There are two main types of insulation in running jackets: down feathers and synthetic. Our Best Insulated Jackets for Running guide explains how the two types of insulation work.

Down insulation is made of feathers from geese and ducks and provides a lot of warmth for minimal weight. Unfortunately, down loses its insulating properties when it gets wet, as the feathers clump together and can no longer trap air between them. Whether down gets wet from sweat or rain, it stops keeping you warm, making it a less-than-ideal option for running jackets. Still, a down jacket like the Mountain Hardwear Ghost Whisperer Hoody can be a good choice for fastpacking when weight and volume are important.

While heavier and bulkier than down, synthetic insulation is often a better option for cold-weather runners. It generally features polyester shaped to mimic the air-trapping qualities of feathers. Synthetic insulation will maintain its insulative properties even if it gets wet and appears in more technical insulated jackets. A lightweight insulated jacket, like our favorite, the Patagonia Nano-Air Light Hybrid Hoody, can provide a lot of warmth for the weight, and you don’t have to worry about sweating in it.

Since running is inherently a high-aerobic output activity at a relatively low speed, it doesn’t require as much insulative warmth as other sports, such as cycling or skiing. Many insulated running jackets are only insulated in certain areas to help with breathability and comfort. Extra insulation around the core can keep your body warm without adding extra bulk around your arms.

Breathability

If a jacket doesn’t breathe, it’ll keep any sweat and moisture from your skin trapped either in the layers you wear underneath or on your skin itself. A non-breathable jacket will leave you soaked and cold, ultimately defeating the purpose of having a jacket on in the first place. The best running jacket will protect you from the elements while allowing water vapor to move from your skin to the outside. We were impressed with the breathability of the Patagonia Houdini Jacket, which provides lightweight wind protection.

Moisture Vapor Transmission Rate (MVTR) is a breathability measurement that determines the amount of water vapor a material can allow through. It is measured in grams of vapor per square meter of fabric per 24 hours. A moderate breathability rating starts at around 10,000 g/m² and increases as the material becomes more breathable. While lab testing is a good baseline for assessing a material, real-world testing is the best way to determine how breathable a jacket is. You can read more about these measurements in our Best Running Rain Jackets guide.

Waterproofing and Versatility

Most runners don’t want a closet full of jackets, and some only want one or two options to keep things simple. When it comes down to it, many jackets can work in a variety of situations, just not optimally. A rain jacket can also act as a wind jacket; it may just be a bit heavier and not breathe as well. A windbreaker with a DWR coating, like the Montbell Tachyon Hooded Jacket, can provide some protection from rain but will ultimately leave you soaked if it doesn’t let up. Both windbreakers and rain jackets provide warmth, but neither will be as warm as an insulated jacket. A waterproof insulated jacket will offer the ultimate protection from whatever nature throws at you but may be too warm and heavy for most running scenarios.

If you’re looking for one type of jacket that can do most things, consider a lightweight, waterproof rain jacket. We have lots of options listed in our Best Running Rain Jackets guide. While you may be carrying around more jackets than you need for chilly runs, and it definitely won’t breathe as well as just a windbreaker, you can trust a rain jacket to keep you warm if the skies open up. It’ll also provide adequate warmth in most running conditions.

DWR Coatings versus Waterproofing

If you frequently run in rainy conditions, you’ll want a fully waterproof jacket like the Patagonia Storm Racer Jacket that you can trust to keep you dry. Fully waterproof jackets generally have multiple layers and are classified as one-, two-, 2.5-, or three-layer jackets. You can read more about the layers used in these types of jackets in our Best Running Rain Jackets guide.

Many running jackets, including most windbreakers, have a DWR coating on the outside. This highly hydrophobic coating causes water to bead up and slide off instead of getting absorbed into the material. Jackets with DWR coatings provide adequate protection in many slightly rainy scenarios and are generally lighter and more compact than full rain jackets. The coating can wear off over time but can be renewed with a product like Nikwax. Many jackets, including the Patagonia Nano-Air Light Hybrid Hoody and the Patagonia Houdini Jacket, use a PFAS-free DWR coating on their outer layer, a more environmentally friendly option.

Sustainability

Many companies are striving to make their products more environmentally friendly and sustainable. One way they’re doing this is by using recycled polyester for insulation. The Patagonia Nano-Air Light Hybrid Hoody uses 93% recycled polyester for insulation.

The use of PFAS-free DWR coatings is also a big step toward making jacket manufacturing more environmentally friendly. Perfluorinated compounds are highly hydrophobic, which is why they have been used to make a material water repellent. The byproducts of the manufacturing of PFASs are highly toxic and difficult to dispose of.

Why You Should Trust Us

At iRunFar, we understand the importance of a jacket you can trust to keep you safe and warm. A windbreaker with a hood that flaps in the wind might only be a minor annoyance, but a rain jacket that soaks through in a downpour or an insulated jacket that isn’t warm can lead to a dangerous situation before you know it.

To find the best running jackets on the market, we asked our team of trail, road, and ultrarunners to tell us about their favorite jackets — old workhorses that have provided years of protection and warmth and newer additions to their closets. We also researched new and updated additions to the market from brands traditionally known for their running attire and companies catering to the Nordic skiing crowd. Our testers took jackets out in all conditions, from California to Oregon to Colorado and Utah, and even to New Zealand, to rate them on their performance, comfort, and durability. We tested jackets in many conditions, from chilly but dry nighttime runs to multi-day fastpacking trips through the Wind Rivers under days of soaking rain.

As brands continue to update and release new jackets, we continually test the best and update this guide accordingly. Testing is ongoing as our writers, testers, and editors are constantly trying out new products in many different climates and weather conditions.

Frequently Asked Questions about Running Jackets

When should I wear a jacket while running?

When temperatures drop, the wind picks up, or the rain starts to fall, a jacket is your best bet for protection against the elements. While putting on an extra shirt or relying on a plastic poncho can get you some protection, an excellent running jacket can provide comfort and safety. In many cases, there’s no need to take a jacket along for a run if it’s short and local, but they are a key piece of safety equipment when venturing far from a trailhead or when the weather is unsettled. Many trail and ultrarunners keep a lightweight jacket, like the Montbell Tachyon Hooded Jacket, permanently stashed in their running pack as a just-in-case essential piece of gear.

What jackets are suitable for running?

Runners recreate in all types of conditions and must choose the best running jacket for their needs. For the vast majority of scenarios, a simple windbreaker such as the Patagonia Houdini Jacket is all that is needed to stave off the chill of an early morning jog or provide enough warmth to traverse a rocky and exposed ridgeline before dropping back into the protection of the trees. These types of jackets are lightweight, breathable, and packable, so they are easy to carry and comfortable to wear in various conditions. Many of them come with a DWR coating, making them somewhat water-resistant.

But as conditions worsen, you’ll have to consider your jacket choices more carefully. Will a run be rainy enough to warrant a full waterproof jacket? Will it be cold enough to choose an insulated jacket to provide extra warmth from the chill? Do you need a hood for even more warmth and protection from sideways wind, hail, sleet, or snow?

No jacket will be ideal for all conditions, so it’s important to consider the specific weather conditions you need protection for. If you know you will be headed out in the rain, consider a fully waterproof option like the Patagonia Storm Racer Jacket. And if you’re looking to stay warm in the coldest conditions, having an insulated jacket like the Patagonia Nano-Air Light Hybrid Hoody on hand can make the difference between shivering and comfort.

What are the different types of running jackets?

While there are seemingly endless variations on the theme of the best running jacket, most runners will find that having two to three options on hand will cover most conditions.

Lightweight windbreakers are the most common type of running jacket. The Patagonia Houdini Jacket is a long-time favorite of the ultrarunning community. Brands design windbreaker jackets to be nearly weightless, small enough to fit into a pocket when not used, and provide extra warmth when temperatures drop or the wind picks up. Some windbreakers have a DWR coating to provide rain protection in case of light and passing drizzle. You can find more options in our best windbreaker jackets guide.

Rain jackets are an essential piece of gear for many runners and are generally required for races with a mandatory gear list. These jackets have various levels of waterproofness, with the waterproofness of a material being measured by its hydrostatic head. Lightweight waterproof jackets tend to soak through more easily than heavier ones, and most mandatory gear lists for races have a certain waterproofness level required in a rain jacket. The ultralight Inov8 Raceshell HZ will meet most gear list requirements, but it’s always good to double-check. You can find more options in our Best Running Rain Jackets guide.

While runners tend to generate a lot of body heat and generally don’t need an insulated jacket until temperatures get really cold, it remains a critical piece of running gear for those living in colder climates and for those who run in remote locations where getting hurt could result in a many-hour wait for rescue. A jacket with synthetic insulation, like the Patagonia Nano-Air Light Hybrid Hoody, will stay warm even when wet and is a better if heavier, option than a down jacket.

How should I layer while running with a jacket?

Choosing layers to wear under a jacket is critical for long- and short-term comfort. Wearing too few layers can result in getting cold, and wearing too many layers can result in sweating through them all and still getting cold. While each person has a different range of comfortable temperatures, a light jacket paired with a thin base layer will provide enough warmth for conditions down to about freezing. As temperatures drop below that, you’ll want to consider adding an extra insulating layer under your jacket or wearing a jacket with synthetic insulation. The Patagonia Nano-Air Light Hybrid Hoody is an excellent option for a warmer jacket.

If the outside temperatures dictate the need to wear a jacket, paying attention to internal body temperature regulation is also important. If you start to sweat, you’ll want to dial back your effort level to reduce the heat you’re producing or take off a layer. Sweating through a layer is a quick way to render it ineffective and should be avoided whenever possible. This is especially true if you’re wearing a down jacket like the Mountain Hardwear Ghost Whisperer Hoody. You can always put a dry layer back on if you get cold, but once it’s wet, your options for layering become much more limited.

Are there warmth ratings for jackets?

While there is a unit of measurement for a garment’s warmth called its CLO, using just this rating to choose a jacket leaves much to be desired. This measurement is generally only discussed regarding insulated jackets. Since everyone runs at different body and outdoor temperatures, hard and fast ratings for jacket warmth and layer options aren’t terribly useful. You’ll have to determine what works for you and in what conditions.

Down jackets, like the Mountain Hardwear Ghost Whisperer Hoody, have a fill-power and fill-weight rating. Fill power determines the quality of the down used in the jacket, and fill weight is the amount of down in the jacket’s baffles. Higher numbers for both ratings indicate a warmer jacket.

Synthetic insulation is measured in grams per square meter (gsm). Again, the higher this number, the warmer the insulation and, most likely, the jacket.

Do I need a breathable jacket?

The breathability of a jacket is of utmost importance. If moisture can’t escape through a jacket’s material, sweat will absorb into whatever layers you’re wearing and accumulate on your skin. This can be incredibly uncomfortable and potentially lead to an unsafe situation if you get too wet and cold. A highly breathable jacket will keep the microclimate around your body warm and dry. Jackets with vents and pit zips can help you dump excess heat as you warm up. Anorak-style jackets without a full zipper, like the Inov8 Raceshell HZ, make temperature regulation more difficult than with jackets that have a full zipper. A hood can also help with temperature regulation.
