Moisture-wicking layers are the key to cold-weather running. We’re partial to pieces that feel cozy and soft but are still breathable and adorned with thoughtful technical features. That can be a tall order, but these products hit the mark—and they look good, too.

This 100 percent merino-wool bra offers enough compression and support for medium to large chests without squashing or sacrificing comfort. The tagless, seamless design prevents itchiness or chafing, and you can wear it all day—the wool dries quickly without leaving sweaty smells behind. (S–XL)

This merino and polyester top with mesh panels on the sides kept our body temperature just right on a wide range of winter days, and it didn’t get stinky even after multiple wears. Don’t be scared off by the mock turtleneck: it’s surprisingly flattering and great at shutting out the first blast of cold air as you head out the door. (XS–XL)

This midweight, stretchy full-zip fleece makes you feel cozy without overheating. Snow flurries brush right off the DWR-treated fabric, and hip pockets store gels or a phone, and the hood fits snugly. (XS–XXL)

This stretchy, three-layer waterproof shell offers the perfect mix of protection and breathability for rainy or snowy sessions. An attached pack-away pocket lets you store the jacket in the pocket of your leggings. (XS–XL)

Woven knit on one side and recycled fleece on the other allows you to turn this hat inside out depending on whether you want a little or a lot of insulation on your head. It fits over your ears without itchiness and doesn’t shrink in the washing machine.

Long runs are no match for these toe socks, which reduce friction in between your digits. (No blisters!) The cushioned terry material softens impact. Extra compression on the footbed offers arch support, and the mini-crew height means no chilly bare ankles.

This vest has a large vertical compartment for poles, easily reachable side pockets for layers, and several spots to carry snacks up front. Two water-resistant shoulder pouches protect valuables, and the hourglass-shaped 1.6-liter bladder is less prone to sloshing. The back panels are tapered so there’s less room for moisture to cling to you. (XXS–XL)

These are the holy grail of winter running leggings: warm and thick for the coldest days, but not restrictive. The stretchy fabric—a mix of recycled polyester, wool, and elastane—resists funk even after several runs, and a wind-blocking layer on the front stops chills on gusty days. The fit is high-waisted and there are four pockets, including one zippered, sweat-resistant one for your phone, plus reflective trim for visibility. (XS–L)

This is the glove you can put on before you’ve warmed up and keep on for your entire run without getting sweaty. If conditions turn, deploy the DWR-coated mitten flap hiding on the back of the hand. We also love the reflective stripe, smart-touch-enabled fingertips, and cuff that covers your wrists.
