5 best running jackets, reviewed by Glamour's most active editors
So you watched 57k people finish the London Marathon, and you're feeling inspired. First thing you'll need? A running jacket for waterproof protection — closely followed by an ultra-light base layer, durable running trainers and a supportive sports bra. But what should you consider when shopping for an active overlayer?
“Altogether, the right running jacket should feel protective, adaptable, lightweight, and secure — giving you confidence no matter what the weather brings,” says Jeff Garabedian, New Balance's General Manager, Fields of Play — Running Apparel. Noted. Although I'd also recommend finding one you feel cute in, because what better motivation to rack up some miles on windy days or during wet weather? Yep, we're ditching the run-of-the-mill, generic rain jackets that make you look a little bit like a lost hiker.
Instead, I've spent the last three months layering up to test a host of running jackets to discover the best overall for trail running, cold-weather road running and race days. That involved trawling the virtual aisles and personally testing a host of lightweight windbreakers and packable running jackets finished with reflective details to see which scored high in terms of quality, safety and style.
So, read on to discover the best lightweight jackets for weather protection in 2026, some with adjustable hoods or zip pockets and others with handy thumb holes. But I've also sought out answers to common FAQs from industry experts, and if you're questioning which gym leggings and running shorts to call on ahead of your next training block, I've got you covered there, too.
Ahead, the best running jackets to shop in 2026, reviewed:
lululemon has long been one of my favourite activewear brands, loudly praised by my fellow editors and me for its high-quality, high-performing gym leggings and sports bras. However, this zip-up jacket is regularly called on, too. Offering gentle compression without limiting any movement, this close-fitting jacket is uber comfortable and flattering. More importantly, though, is the fact that it works for throwing on for a chilly 5K, as it does for wearing over your yoga kit. Not once did it lift, twist or come undone, even during speed sessions or a sprint finish. But, it also wasn't too hot or bulky to wear for a weight HIIT session at 1Rebel. I also appreciated the addition of thumbholes for keeping my hands warm, plus the zipped front pockets are big and secure enough to hold your phone, headphones or gels, allowing you to skip a running vest.
Available sizes: 0 (UK 4) — 14 (UK 18).
Material: 81% nylon, 19% Lycra elastane.
Colours: 8.
Care: Machine wash cold.Save when you shop for the best running jackets with these lululemon discount codes at checkout.
Pros & ConsPros- Sits below the waistband for moderate, everyday coverage — but this also helps prevent any middriff flashing.
- Crafted from buttery-soft and weightless Nulu fabric.
- Zipper garage limits chafing at the neck.
- Elastic zipper pull doubles as an emergency hair tie — genius!
Cons- An investment — but it will last.
Amazon Essentials Women's Active FormFlex Buttery Soft Slim Fit Full Zip Jacket
I hear you if you don't want to spend a fortune on activewear, considering it's either in the wash or worn to get your sweat on. Thankfully, Amazon Essentials has delivered a range of high-performing separates, most of which come in at under £30. This zip-up jacket — fairly similar in style to the lululemon Define — is sculpting but not at all suffocating, and so you should also have no concerns about it limiting your movement. Cut with a longer body length and designed to hug your hips, it didn't ride up or twist once during my 10k. The thumb holes also help keep the sleeves in place, while the zipper garage prevents any irritation at the neck — plus, the slightly thicker, almost scuba-like materials offer an added layer of warmth on colder days. Essentially, I don't have a single complaint — not one.
Available sizes: XS (UK 8-10) — XL (UK 22-24).
Material: 79% nylon, 21% elastane.
Colours: 4.
Care: Machine wash cold, tumble dry low.Save when you shop for the best running jackets with these Amazon discount codes at checkout.
Pros & ConsPros- Moisture-wicking and quick drying.
- True to size and size inclusive, available in every size from a UK 8 — 24.
- Super affordable and so a great option for beginners.
- Available with next-day delivery for Prime members.
Cons- Stock is intermittent and limited.
On is to thanks for one of my favourite pairs of running shoes — the Cloudmonster 3 are engineered for forward momentum, the rocker-style sole propelling you forward. And now the brand has launched a running jacket to match. Like many others in this edit, it's made from polyester fitted with four-way stretch, but cut looser and so is more suitable for those not seeking a sculpting design. But its also lightweight, breathable and waterproof — even during an unexpected April shower, my underlayers were only damp from sweat and not soaked through. The addition of multiple waterproof pockets is much appreciated, effectively keeping my sweat towel and emergency Percy Pig stash dry too!
Available sizes: XS (UK 8-10) — XL (UK 22-24).
Material: 79% nylon, 21% elastane.
Colours: 4.
Care: Machine wash cold, tumble dry low.Pros & ConsPros- Fitted with reflective stripes on the arms for boosted visibility.
- Elasticated hem keeps the jacket snug.
- Water-resistant zippered pockets keep your belongings dry.
- Shaped, elasticated hood stays in place — even while interval training.
Cons- The most expensive in this edit.
UV-Protective Cinch-Waist Running Jacket
I'll be honest: despite our beauty editor waxing lyrical about the importance of SPF, I rarely apply it anywhere except my face pre-run. Personally, I find it only works to make me feel sweatier. Thankfully, this lululemon jacket offers UPF 40+ protection, while also acting as a water-resistant top layer. I love the adjustable cinch-waist detailing — it's both a bang-on trend, super flattering and works to prevent unnecessary flapping while on the move. I do wish the elastic around the wrists were a little tighter to prevent cold winds and rain moving down the sleeve, but that was my only major concern. However, I loved the blue hue (a fun alternative to black) and the option to coordinate my running shorts. Even better news: this running jacket comes with eco-credentials, considering 100% of the polyester and nylon in this product is recycled.
Available sizes: XS (UK 8) — XL (UK 16-18).
Material: 86% recycled polyester, 14% elastane.
Colours: 4.
Care: Machine wash cold.Pros & ConsPros- Customisable fit, thanks to that interior waist drawcord — which also prevents unnecessary flapping.
- Sweat-wicking and quick-drying.
- Interior chest phone pocket.
- Matching shorts available.
Cons- Limited size range.
My pet peeve when running outside? Despite checking the temperature on three apps and evening standing outside to assess the chill, I can still get my outfit entirely wrong. Thankfully, this packable Free People jacket folds down to no bigger than a fist, meaning you can attach it to your running vest, calling on it when needed. However, the brand also hasn't scrimped on the details in order to save space. Fitted with a stand-up collar to help control your core temperature, and adjustable bungee sleeves, this was celarly designed by fellow runners. However, it also boasts natural wool insulation for added warmth, yet is still super quick-drying. And fitted with bungee detailing there's the option to customise the fit, too.
Available sizes: XS (UK 4-6) — XL (UK 20).

Running jacket FAQs, answered:
“A great running jacket really comes down to how well it supports you through changing conditions, and that starts with comfort and protection,” says Jeff Garabedian, New Balance's General Manager, Fields of Play — Running Apparel. "When you’re out on a run, the weather can shift quickly, so having a jacket that you can move freely in that also shields you from the elements is essential.
“Beyond comfort and protection, packability is a major factor. A jacket that’s easy to pack on the go gives you flexibility without weighing you down or forcing you to commit to wearing it the entire time. The NB RC Jackets are a strong example of this idea in action — they’re designed to pack down effortlessly into a mesh pocket, making storage simple and intuitive. Once packed, the jacket can be carried using an integrated strap, which means you don’t need a bag or extra storage to keep moving comfortably.”
One more thing to consider? Fabric. “Lightweight fabric is another key feature to look for,” adds Jeff. "A jacket that feels light helps maintain that ease of movement and prevents that heavy, restrictive feeling that can make a run less enjoyable.
“Finally, details like an elasticated hood, cuffs, and bottom hem help offer added protection from the elements. These features work together to ensure the jacket stays secure and functional, even when conditions aren’t ideal.”
JJ Collier, VP, Outerwear Design at lululemon, adds: "With high performance and high style in mind, we put the experience of the athlete at the centre of our work. We start with selecting materials that will provide solutions for various conditions and climates. The fit and style needs of various markets are also considered.
"We study details like reflectivity, cinchable hems, secure pockets, and hidden phone sleeves that all help make the jacket functional. Simple solutions, like hoods that can be cinched at the back to help maintain peripheral visibility — as seen on our Lightweight Waterproof Running Jacket — are also central to the experience. Our Rain Chaser Jacket even has pockets that double as vents to help cool your core and keep the garment light.”
But we also asked Haley Thompson, Senior Designer at Oner Active to weigh in: 'The features I would look for in a running jacket would include one that is lightweight and body skimming so it feels comfortable without being bulky or heavy during exercise.
"I would also want mesh panels or ventilation areas to improve breathability and help regulate body temperature while running. Flexibility is important, so the jacket should allow easy arm movement without feeling restrictive. An optional hood is useful for unpredictable weather and longer sleeve cuffs with thumb loops can help keep my hands warm during colder runs.
“I also like a drawcord waist because it helps cinch the jacket closer to my body and prevents cold air from getting inside. Reflective accents are another important feature because they improve visibility and safety when running at night. Hidden pockets are also very useful for storing small essentials such as my phone, house key, or lip gloss while keeping my hands free.”
“The fit of a running jacket ultimately comes down to personal preference, and the season you’re running in,” continues Jeff. " Some runners prefer a looser fit because it gives them the flexibility to layer underneath. This can be especially helpful in colder months when you may want to wear additional layers or even a hydration vest without feeling restricted. A loose jacket can accommodate those extra pieces comfortably while still offering protection from the elements.
“On the other hand, a more fitted jacket helps reduce bounce and distraction while running. This streamlined feel is often the preferred option for runners who want minimal movement from their gear. Whether you choose standard or fitted, the goal is to find a jacket that supports your run without getting in the way.”
“It comes down to personal preference and what you need from your jacket. A closer fit can work really well for colder runs, when you want to keep warmth close to the body and minimise distractions with a more streamlined feel. In warmer weather, a more relaxed fit can be a great option, as it allows for better airflow and feels light, airy and easy to layer.”
JJ adds: "It comes down to personal preference and what you need from your jacket. For lululemon, that means giving our guests various styling options and features — like hem cinches — that allow the wearer to personalise their look or adjust to varying conditions.
“A closer fit can work really well for colder runs, when you want to keep warmth close to the body and minimise distractions with a more streamlined feel. In warmer weather, a more relaxed fit can be a great option, as it allows for better airflow and feels light, airy and easy to layer.”
Haley, instead, suggests looking for something in between: "A running jacket should fit somewhere in between tight and loose. If it is too tight, it can feel restrictive and uncomfortable, making it difficult to move naturally while running.
“A jacket that is too loose may create drag from the wind and could slow you down or feel distracting. The ideal running jacket should fit close enough to the body for comfort and performance while still allowing enough room for movement and layering underneath if needed.”
“There’s often confusion around the difference between waterproof and water-resistant jackets,” explains Laura Drane, Performance Designer at Sweaty Betty. "A waterproof jacket is designed for heavier rain and gives full protection from wet weather, through more technical fabrics & sealed seams that stop water getting through. The trade-off, however, is that fully waterproof fabrics are often less breathable, meaning heat and sweat can become trapped inside during longer/ higher-intensity runs.
“Water-resistant styles are better suited to lighter showers or changeable weather and are often softer, lighter and more breathable to run in day-to-day. Many water-resistant jackets are finished with a DWR (Durable Water Repellent) coating, which helps water bead and roll off the surface of the fabric rather than soaking straight through. They won’t keep you completely dry in prolonged heavy rain, but for many runners they strike a really good balance between protection, comfort and breathability.”
Jeff adds: “The difference between waterproof and water‑resistant running jackets comes down to how much protection the garment provides. A waterproof jacket uses fabric with a true waterproof quality, often achieved through a specific layer or membrane that prevents water from passing through.
"For a jacket to be fully waterproof, it also needs sealed seams, which stop water from entering through stitching or zipper constructions. This level of construction is designed to keep you dry even in heavy or sustained rainfall.
“A water‑resistant jacket, by contrast, is built to handle lighter conditions. It can resist water to a certain degree — such as a light rain shower — but it’s not intended for heavy or prolonged rain. Water‑resistant jackets are great for mild conditions where you want some protection without the full structure of a waterproof piece.”

How I test the best running jackets:
After calling in a sample from a brand, I'll aim to wear each running jacket for three runs: a 5k on the treadmill, a longer run outside, and a hybrid workout, such as Reshape at 1Rebel, to see how it fared when my arms weren't only swaying at my sides.
After wearing each jacket for at least three runs, both on the treadmill and outside, I reviewed it against the following criteria:
| Design | Is the running jacket fit for purpose — is it sweat-wicking, water-resistant or waterproof? Is it true to size and comfortable to wear for long runs? Do I have options in terms of colour and design? |
| Fit | Is it true to size? Are there petite and tall options? Is the sizing and associated guide easy to understand? Does it fit comfortably close to the body with minimal flapping in the wind? Does it allow for a full range of motion in the shoulders and arms? |
| Price point | Would I be willing to spend that much on a running jacket again? Did it wear and wash well? |
| Delivery | How quickly did the running jacket arrive, and what were the associated costs? |
But, because we're all different in terms of our body shapes, sizes and favoured styles of activewear, I also asked my fellow shopping editors to weigh in with their favourites. This dictated what styles and brands I reached out to for samples.
As you'd hope, only the running jackets that impressed made it into this edit. However, I also tried the following, which sadly didn't meet my standards:
- TALA's DayFlex Zip Through Sports Jacket, £69 — Considering TALA is one of my favourites for scrunch-bum leggings, I had high hopes for this sports jacket. However, the cropped style makes it wholly unsuitable for running, regularly riding up to reveal my midriff. There's no denying it's great quality, but I'd say it's best suited to low-impact workouts like Pilates and yoga.
In terms of what I'm currently testing, stay tuned for these reviews:
Why you can trust me:
I've been a shopping writer for almost three years — that includes a year writing for Cosmopolitan and Women's Health, followed by 19 months at Glamour. In that time, I've reviewed everything, from the latest activewear, including gym trainers and Pilates leggings, as well as menstrual products like period pants and sexual wellness launches.
In terms of my working week, it consists of a lot of personal testing, plenty of writing and heading to countless press events to catch up with brands and experts on their fresh releases. I also regularly chat one-on-one with activewear designers, women's health experts and functional fashion pros, asking for their expert insight. I also try to keep up to date on the latest wellness research, scanning journals and scouring the internet for fresh stats.
However, I'm also addicted to endorphins, working out up to five times a week. That includes attending weighted HIIT classes at 1Rebel and F45, interspersed with regular 5k runs. I'm also due to run the Royal Parks Half in October, so I am currently trying to up my speed before embarking on an intense training block from August. So, you could say I'm clued up when it comes to running gear, considering I call on mine at least three times a week.
