How to Choose the Best Running Jacket


In this article we will discuss how to select a running jacket that suits your needs and running style. After putting nine of the top rated and most popular running jackets through a rigorous three month testing period where we ran through rain storms, freezing temperatures, high wind and tackled both urban and backcountry running environments, we felt we had a comprehensive idea of what each of the products could offer. We aim to walk you through the process of deciding what your needs are as a runner and which jacket will satisfy those needs. The running jackets we focused on are those that offer some degree of breathability, weather resistance, and comfort to offer protection from the elements during high output aerobic activity when you're generating an excess of heat and sweat. Continue reading to learn what to look for when hunting for a running jacket.

The jackets of today are made of highly breathable material and some have venting placed in strategic areas to dump heat and moisture  letting you concentrate on your run  not on regulating your temperature.

We all remember the track suits of the 1990s. They were constructed from thick nylon and had no weatherproof treatments applied to them. Essentially they were just "warm ups" that you would wear at the start of your aerobic exercise and then ditch before the main show. Another option at the time was to wear 'sweats' for your workouts. Ignoring the fact that sweats are/were extremely heavy, they also absorb moisture and refuse to let go. Somewhere along the line it was decided that we the people really needed a jacket that could offer some protection from wind and rain, but also provide the breathability of natural fibers that aren't suitable for battling the elements while maintaining the lower weights of synthetic fibers. Fast forward to 2017. We have synthetic fabrics that are so thin and lightweight there is potential for an entire men's size large jacket to weigh as little as one ounce. Through this evolution of fabrics DWR treatments were developed allowing fabric to become water resistant and retain breathability.

What necessitates a running jacket? It is impractical to carry along multiple jackets to handle different situations when running. A well balanced running jacket should offer some degree of weather protection, significant breathability, and be easy to transport when you aren't wearing it. This is true if you're out for your morning jog or if you're on loop 3 of the 160 mile Barklay Marathons. Running is a situation where a "jacket of all trades" is necessary.

What sets the running jacket genera apart from other jackets such as rain jackets or soft shells? Running jackets are designed with one purpose in mind and that is to provide protection from the elements while running. This means providing resistance to the elements while being able to handle the huge excess of heat and moisture our body's release when in an aerobic state. Rain jackets do a similar job but the ability to vent and breathe has been turned way down, whereas the water resistance has been cranked to eleven. Soft Shell jackets are tuned more towards breathing but are typically created from multiple layers and are suited for much colder environments than your run of the mill running jacket.

Venting and Breathability


Breathability is the single most important aspect of a running jacket. Running is a highly aerobic exercise which will cause you to sweat heavily. Even if you don't sweat much, the excess heat and moisture are being released. No matter how a jacket may protect you from the elements, if you are wearing a layer that restricts airflow, or doesn't allow moisture to dissipate, you're undermining the purpose of wearing a running jacket. We start with venting and breathability because the majority of your running will not be done in inclement weather and since our goal is to remain as dry as possible our jacket must be able to handle the excess heat and moisture. Hands down the most breathable and well ventilated jacket this year was the Outdoor Research Boost It had an uncanny ability to keep us dry on intense uphill slogs.

Throughout our testing process, we discovered that breathability depends not only on the jacket construction and fabric type, but also on its ability to vent well. Some fabrics themselves are designed to wick away moisture, but not all. If the fabric doesn't do this, it's up to the ventilation design to provide enough air circulation to pull out as much moisture as possible. Mesh panels are a common method of venting moisture, as well as vent flaps that overlap the fabric. The placement of the mesh or breathable panels is critical for the breathability and ventilation of the jacket. Even if you don't sweat a lot in general, when you're travelling uphill and your heart rate is at its max, you will be surprised with the differences between a jacket that is properly vented and one that isn't. During this test the proper quantity and placement of ventilation and use of breathable material made a massive difference if the buildup of heat and moisture. To put it plainly, breathability and venting is a top priority in running jackets. When you are selecting a jacket, use the amount of ventilation on the Outdoor Research Boost as a guide. Upon first glance you might think the venting is excessive, but it isn't.

Everything grey on the OR Boost is venting. You can think of the grey as mesh, though it's comprised of a very stretchy synthetic blend. While the Outdoor Research Boost might be knocking on the door of having too much ventilation, it hasn't crossed that threshold. It's as breathable as a fleece jacket while providing weather resistance to boot.

Weather Resistance


Getting a running jacket that doesn't offer you any protection from the elements undercuts our goal of being able to remain as dry as possible and run as much as possible. If you don't have the option of running when it's drizzling outside because, for example, you only have a fleece to run in, you're missing an opportunity. Assuming your jacket offers you the necessary breathability as discussed above, weather resistance is the next most important attribute to look for. Before we get too deep into weather resistance, know that none of the running jackets we tested were waterproof. The standout in weather resistance was the Arc'Teryx Incendo. This jacket kept us dry longer in driving rain and repelled wind with the best of the rest of the pack.

They aren't a substitution for a rain jacket that would commonly be used for other outdoor purposes. If you go for a run in pouring rain for more than a few minutes you will get wet. That being said, most companies use a DWR finish added to their jackets to repel water. This technology does work fairly well and has the benefit of adding weather protection to a single layer of fabric, however it does require some maintenance. After some time, the DWR finish will wear off and it's up to you to use a special wash that is specially designed to not leave any residue on your technical gear, and then reapply the DWR coating (which can be found as a spray-on or wash-in product). Some pieces use a combination of DWR coating and specially designed fabrics to accelerate the evaporation time, sometimes using the runner's body heat to further aid the already accelerated process. The Arc'Teryx Incendo proved to have superior weather resistance compared to the rest of the jackets.

As far as wind is concerned, the goal is to find a jacket that buffers the wind and keeps it from battering you. Finding a completely windproof jacket would most definitely hinder the breathability of a running jacket. Check out our wind jacket review if you are looking for something that is completely windproof. While offering substantial wind resistance is desirable, the real goal is to find the jackets that pair wind resistance with breathability and venting. Strategically placed vents are the key. Making a wind resistant jacket doesn't seem to be a challenge, companies were accomplishing that in the 70s and 80s. We want a wind resistant jacket that is as breathable as a fleece. The Outdoor Research Boost has accomplished just that. They place windproof panels strategically as to retain the jacket's breathability and protect the wearer from harsh wind.

Comfort and Mobility


While things like Fit and Mobility are going to vary for each runner, there are aspects to the comfort of the jacket that are going to be pretty constant. Things like encorportating stretch material into the design as well as joining panels with seams strategically placed so they don't come in contact with skin in irritating ways. Throughout the testing process it became apparent that some of the jackets were designed with movement in mind. It's important to find a jacket that doesn't just feel good while you're standing in the department store. We found that one of the most important aspects of finding the right running jacket was finding one that we didn't really notice while we were running. Those jackets typically had a semi-loose fit, and incorporated sewing patterns that had soft seams and stretch material. That's not to say that if a jacket doesn't have stretch material that it won't be comfortable, but as a general rule, those jackets that did have stretch panels were more comfortable for all day excursions.

As we examined our perceived comfort of each jacket  we looked into why certain aspects of each jacket are comfortable or not. Top image Outdoor Research Boost. Bottom image Agile. The different stitching styles proved to create dramatic differences in comfort.

Portability


The bottom line for running jacket portability is that we need to be able to bring our running jacket along on our run, deploy it at a moments notice, remove it, and repack it all without any drama. If a jacket doesn't meet these criteria it just isn't worth the effort to bring it with you. For example, the North Face Better Than Naked is a fine jacket if we just look at the jacket's breathability and weather performance. Would we bring it with us on a trail run? No. Because the closure system when the jacket is packed into its stuff pocket consists of a single sided zipper pull and we have trouble opening and closing it.

Notice the zipper on the Better Than Naked jacket has a one sided pull. We found it difficult to open and close this stuff pouch.

We require that our jacket be both functional and very easy to use. We especially appreciate the stuff system on the Montane Featherlite 7 and the Outdoor Research Boost since neither require a zipper and we could make them both function with gloves on. They may not be the prettiest closure systems but they are probably the most functional. If portability is a top priority check out the Montane Ultralight 7. It was our top pick for portability and offers excellent protection and nearly half the weight of the next lightest jacket in our review.

This brings us to the weight of the running jacket. Every ounce counts when you are running. Ten miles into a run, everything you have with you begins to feel heavier. That being said, our goal is to make sure that every ounce we are carrying has a purpose. Don't just get the lightest jacket because it is the lightest. Get the lightest jacket that retains all of the functionality that you need. Our go to jacket is the Outdoor Research Boost which weighs in at 5.2oz which sounds like a lot compared to the Montane Featherlite 7's 1.6oz. Indeed it is a big gap, but we feel that the extra cost in weight is justified by the attributes offered by the OR Boost. If you know that your jacket will be reserved for emergencies the Montane Featherlite is an excellent choice.

Day and Night Visibility


Safety is a primary concern when running both in urban environments and out on the trail. Ideally your running jacket will be your outermost layer and thus will need to provide visibility. Even if you are alert, not listening to music, and aware of your surroundings, other people might not be. Drivers are more distracted today than ever. The brighter and more reflective your jacket the greater chance that driver with a mini van full of youth soccer kids will notice you crossing the street. While there are many things you should do and be aware of while running, wearing a bright and reflective jacket is a passive way to protect yourself from motorists. You should be looking for reflective material on all four planes. You need reflective material in front, back, and ideally wrapping around both arms. The movement and swinging motion of your arms helps the reflective material stand out against other urban reflective materials.

The day and night visibility of the Incendo was excellent. The reflective blazing on the wrists was especially helpful in spotting our tester in low light.

During daylight hours the sun washes out the reflective material on jackets and we rely on having colors that stand out against the environment. Having earthtones is not advised as you will blend into your surroundings. One thing the 80's jackets did get right was their incredibly bright florescent colors and random patterns. Our favorite jackets in visibility were the Outdoor Research Boost in its fluorescent green color and the Arc'teryx Incendo jacket. Both had 360 degree visibility at night and bright colors in the day. While there is no way to be absolutely protected while road running, these two jackets certainly give you an edge.

Conclusion


Chosing a running jacket on face value is a mistake. They are all similar priced  similar material  and look similar. Each jacket does come with its own unique characteristics.

Are you looking for a running jacket to wear nearly all the time during cooler weather regardless of rain, wind? If yes then continue reading. If you are looking for more of an emergency weather jacket for running skip to the next paragraph. Look, here's the deal. You want a jacket that is equipped with a high level of breathability and venting. As we stated before, none of these other attributes matter or will even have a chance to help you unless you are wearing the jacket. If the jacket isn't breathable to a high degree you will remove it as soon as you start to sweat. After selecting a breathable jacket, take into consideration what your primary running climate will be. Do you live in Seattle? Your next step will be finding the most water resistant jacket you can find. Keep in mind, the more weatherproof, probably the less breathability and venting you will get and vice versa. After selecting a breathable and weather resistant jacket, you need to dial in the comfort and fit. Don't be afraid to send a jacket back that doesn't fit. Again, if the garment doesn't fit properly and isn't comfortable for your frame, you aren't going to wear it! Finally, if you have two jackets that seem to be equals and can't make a choice, pick the more packable option. When you do remove the jacket, having something that stows easily can go a long way in your overall satisfaction with the product.

If you aren't looking for an all-arounder that can be worn nearly all the time during high output aerobic exercise an emergency weather resistant jacket is warranted. There are several excellent jackets to choose from. These are slightly less breathable but offer greater portability and decent weather resistance. While they aren't suited for prolonged running, they are very lightweight and in a pinch can be lifesavers. The Montane Ultralight 7 stands out as the most portable and weather resistant emergency jacket we tested.
