Men's Double Layer Crewneck

Built for serious warmth, the Men's Double Layer Crewneck features Polarmax's signature double-layer construction — two layers of soft jersey knit connected back to back with open air pockets between them that trap and hold heat close to the body. Acclimate Dry hydrophobic yarns work continuously to transport moisture away from the skin, keeping you dry and comfortable through active use and changing conditions.

The relaxed fit makes this top easy to wear all day on its own or as a dependable base layer under a jacket or outerwear — no restriction, no bulk, just reliable warmth when you need it most. Whether you're on the job, on the slopes, or simply braving a cold commute, the Double Layer Crewneck delivers the warmth and moisture control that gets you through the day.

Polarmax has been making simple, honest base layers in North Carolina since 1985. Parent company Longworth Industries knits, cuts, and sews every piece within a few miles of its Candor, NC mill — 100% made in the USA — and the same factories supply technical next-to-skin gear to the U.S. military. The recipe hasn't changed: soft double-layer fabrics that trap warm air, Acclimate Dry fibers that pull moisture off the skin, and relaxed fits that disappear under whatever the day calls for. At Mountain Sports, we love Polarmax because it's dependable, American-made warmth without the fuss — base layers for the whole family that just work, season after season.
