Winter-training heroes require apparel with oomph.

The North Face Flight Series Fuse Jacket
鈥淏reathable running shell鈥 is usually an oxymoron. Not so the Fuse, which is built from a single piece of fabric with different properties woven throughout. It鈥檚 breathable where you need it to be (along the upper back and under the arms) and聽durable everywhere else. Elastic bands on the hood and cuffs keep out the wet.
Price $250

Patagonia Speed Waffle Crew Shirt
This fleecy pullover feels like a cashmere sweater but performs like a techy racer. Four-way stretch moves with you, underarm gussets vent heat, and the waffle knit is airy enough for hill repeats.
Price $79

Mission Workshop Gobi Beanie
The snug woolen Gobi was designed for cycling but works just as well for running on cold days.
Price $40

Brooks Ghost 9 GTX Shoes
The Ghost 9 is a smooth, light, dependable neutral trainer for the road鈥攁 perennial test favorite that seems to do just about everything well. For winter slush and drizzle, Brooks added a Gore-Tex waterproof upper.
Price $150

Terramar聽Cool-Dry Pro Ankle Socks
Wet socks are a drag. That鈥檚 why we like the Cool-Dry鈥檚 plush poly-wool blend, which draws moisture away from the skin. Just be warned: this thick sock won鈥檛 play nice with low-volume shoes.
Price $26 for 2 pairs

础谤肠鈥檛别谤测虫听罢谤颈苍辞听罢颈驳丑迟蝉
Normally we鈥檙e against running tights. Like, if it鈥檚 that cold, just go skiing. But the Trino won us over. Gore Windstopper fabric across the front repels sleet, while flat seams prevent chafing.
Price $149

Salomon S-Lab Running Gloves
This S-Lab warmer is thick enough to keep you toasty but not so heavy as to hinder dexterity. Credit goes to the crackerjack fabric, which is designed to reflect body heat back toward you, adding warmth without extra insulation. Touchscreen聽compatible fingertips, grippy silicone patches on the palm, and a side pocket for keys complete the package.
Price $50
