Some Days Wind Briefs Just Aren't Enough

Fleece Lined. Wind Resistant. Because wind briefs, long underwear, and other base layers are great, but some days you need more. And, why add extra layers where you don't need them? PolarJock™ is the "Sub-Zero Hero" for cross country skiers and other cold-weather athletes.

Tested on everything from 5Ks to 50Ks, PolarJock™ is constructed for the athlete on the move. Wear one or take one with you so you’re ready when the temperature drops.
