The best long-sleeve running shirts feel great against the skin from the moment you start getting dressed, transforming a winter run from daunting to doable. Once you’re moving, these shirts breathe effectively and help wick sweat from your skin to the fabric’s exterior, where the moisture evaporates into the winter ether. Great women’s long-sleeve running shirts also look good when worn on their own, so they’re able to transition to a post-run coffee or even work as a crossover casual-wear piece. Alternatively, they can serve as a first layer for other activities like Nordic or alpine skiing.
This winter, six running-obsessed testers put this season’s women’s long-sleeve running tops through their paces, tackling roads and trails from Virginia to California. After evaluating and scoring each contender, these are the top-rated running tops we reached for the most.

Material: 37% merino wool, 55% nylon, 8% spandex
Fit: Relaxed
Pros and Cons
+ Excellent warmth and breathability
+ Scuba hood provides added protection
– Expensive
If you buy one running shirt this winter, this top is worth the splurge. Testers said the soft, brushed interior blend of merino wool, nylon, and spandex felt great against the skin and moved moisture to the smooth exterior surface. Extended sleeves and thumbholes kept our hands warm, especially when tucked into gloves (eliminating that pesky gap between sleeve ends and glove cuffs). The scuba-fit hood provided extra warmth and protection for the neck and head, and was lightweight enough not to flop around annoyingly when not in use.
We appreciated thoughtful details like a small interior pocket at the bottom seam with a bungee to attach a key ring, and a ponytail port on the hood. Bonus: The subtle branding, relaxed fit, and overall style also made this a great crossover top for other winter sports or even around-town wear. Another bonus: This shirt, and all Janji apparel, is backed by a 5-year warranty.

Material: 95% recycled polyester, 5% polyester
Fit: Relaxed
Pros and Cons
+ Can be worn year-round
+ Breathes exceptionally well
– Not the softest material
It is hard to find any running shirt for under sixty bucks, let alone one as versatile as the New Balance Athletics Long Sleeve, adding even more value to an already good deal. It’s constructed from a breathable pindot mesh material that breathes exceptionally well and dries quickly. The loose-fit style hits a near-impossible trifecta of fit perfection: comfortable when worn on its own, baggy enough to layer over a tank or tee, and slim enough to fit under most jackets. Because of its light weight and breathability, the shirt can also be worn in the summer months for sun protection.
In chilly weather or at the start of a run, the slightly longer-than-normal sleeves and thumbholes add extra coziness. “The fit of this shirt reminds me of my old baggy long-sleeve cotton t-shirts that I wore running in the evenings in college, and I love that about it,” said a tester. “This one just wicks better and dries quickly.”

Material: Nuyarn 85% merino, 15% nylon blend
Fit: Next-to-skin
Pros and Cons
+ Wool-blend fabric excels at wicking moisture
+ Thumb holes add arm warmth
+ Minimal seams reduce irritation
– Feels bulky when tucked in
– Slightly see-through
The Ibex Pro Tech Woolie Crew felt like it morphed to our bodies—in a good way. Raglan shoulder seams, gusseted underarms, and overall stretchiness created a fit that allowed full mobility, and flatlock seams effectively kept irritation at bay. The running shirt is made out of Nuyarn, a material made by spinning merino wool with nylon so that more of the merino fiber is exposed to air, making it more thermally efficient, elastic, and durable. “This fabric is awesome,” said a tester. “It’s super lightweight, but keeps you warm and dry and has great temperature regulation.” We like the thumb holes that increase arm protection and help keep the sleeves in place while layering.
Another benefit of Nuyarn: It launders well. “This shirt washes very easily, dries on the line quickly, and doesn’t end up all wrinkly, which can happen with wool,” said a tester. That quick-drying property was also appreciated on the run: we never felt cold and clammy in this shirt, and didn’t feel the need to shed it right away post-run.

Material: 94% Polyester, 6% Spandex, bluesign-approved materials
Fit: Semi-fitted
Pros and Cons
+ Incredibly soft and buttery
+ Watch window and thumbholes keep wrists warm
– Not as breathable as some other natural-fiber tops
Testers loved everything about the look, feel, and function of this running shirt from Oiselle. It’s made from insanely soft, buttery fabric that is a joy to pull on, plus the material wicks sweat and dries quickly. Thumb holes on the extra-long sleeves, plus watch windows on both arms, kept cuffs cozily pulled down, with no need to bare wrists to check splits.
The Lite Lux Longsleeve kept testers comfortable when worn on its own in temperatures down to 40˚ in New Hampshire, Maryland, and Colorado. For anything colder, we’d recommend layering under a jacket or midlayer; the shirt’s thin fabric still lets it breathe as a base, and raglan sleeves allow full arm mobility. “I never felt cold or excessively wet in this shirt,” said a Colorado-based tester.
Our New Hampshire-based tester praised its versatility: “I’m always reaching for this shirt first in all sorts of weather conditions. This kind of shirt is one of the first things I’ll pack for any active travel adventure.”

Material: Merino wool, nylon, polyester, and polypropylene in striped colors
Fit: Semi-fitted
Pros and Cons
+ Incredibly soft against the skin
+ Warm and cozy when cold
+ Breathes well when hot
– Can feel wet when sweaty
One of Tracksmith’s original pieces, the Brighton Baselayer’s blend of merino wool, nylon, and polyester feels fantastically cozy against the skin while breathing effectively during aerobic efforts. The weave strategically alternates between perforated, highly porous zones on the upper chest, back, and underarms, and a closed knit on the arms and lower torso that holds in warmth while still letting moisture out. With the fit falling between skin-tight and relaxed, this running shirt can be worn on its own or beneath layers. It’s also cut long at the torso, which makes it easy to tuck in.
This seriously soft running top proved highly versatile. We’ve worn the Brighton Baselayer through six winters, reaching for it often for cold-weather running and as a baselayer while Nordic skiing and snowboarding.

Material: 95% recycled polyester, 5% spandex
Fit: Slim
Pros and Cons
+ High neckline with quarter-zip provides protection and ventilation
+ Textured fabric balances warmth and breathability
– Limited to cold (not cool) weather
We tested a variety of quarter-zip neck tops, and the New Balance Athletics Heat Grid Half Zip was our favorite. We love how its 3D waffle knit fabric holds heat without compromising airflow or weighing us down. “This shirt seemed more breathable than other fabrics that are not textured,” said a tester. “But it’s also really warm, almost like a thin sweatshirt.” The quarter-zip adds additional ventilation options, and thumb holes on extra-long sleeves keep wrists from freezing. A zippered pocket proved to be a convenient, secure place for a key or other small, lightweight items.
“This shirt’s slim fit makes it awesome for layering under something else in cold weather,” said a Colorado-based tester, who wore the shirt on its own in temperatures down to the mid-30s.
Consider your running needs: Are you looking for a baselayer type of fit and function, where next-to-skin comfort and wicking is paramount and a slim fit allows easy layering? Or, are you in the market for a shirt you can pull over a tank or short sleeve? Maybe you want a more relaxed-fitting second shirt to act as a midlayer at times and work on its own when needed.
Think about what added features matter, like thumb holes, hoods, sports watch windows, or zippered necks. Evaluate what materials you prefer against your skin, whether a smooth, airy synthetic fabric or a soft, wicking natural fiber blend.
When possible, head into a specialty retail shop to try on running tops. The one that fits you well, suits your temperature and feature needs, and makes you excited to go running through winter is the best long-sleeve running shirt for you.
Head tester and writer Lisa Jhung researches each gear category and works with gear companies to narrow down which long-sleeve running shirts to add to the test loop. She then orders samples for herself and her team of five testers, who live in Colorado, Virginia, New Hampshire, and the San Francisco Bay Area. For this test, women’s long-sleeve running shirts were worn in a range of winter conditions, from cold, dry, sometimes snowy Colorado Front Range and high country, to cold, damp Atlantic coast and cool, rainy, mild Northern California.
Lisa Jhung has been running for 35 years, testing and writing about gear for 25-ish years, and manages a pool of testers out of her home in Boulder, Colorado. She runs in all conditions and loves heading out in a gnarly snowstorm.
Kristen Mecca moved to Virginia, and then New Hampshire, after running all over Colorado, including multiple podium finishes at the Pikes Peak Ascent and snowshoe races. She now tests gear through the East Coast winter and is staunchly against irritating seams and rough materials.
Vermont-based Lindsay Warner Hrenko puts running gear to the test by logging miles on roads and trails, Nordic skiing, cold-weather mountain biking, and chasing her toddler around. She appreciates apparel that can handle winter in the Northeast while allowing sweat and body heat to escape, and that she can wear to school drop off and not feel silly.
Boulder, Colorado-based Sara Yoder runs road, trail, and crushed gravel around the foothills of the Rocky Mountains. She’s run 11 road marathons, with Boston being her favorite (“because…Boston!”, she says, and also because she ran it with her dad) but now prefers scenic, more casual routes. Still, she doesn’t shy away from an opportunity to toe a starting line.
