More Warmth
Fewer Layers

Finally, men’s base layer bottoms with no bulky layers where you don’t need them. PolarJock® gives you total coverage plus complete freedom of movement and no overheating. This fleece lined base layer is wind resistant yet lightweight and comfortable. For cold weather running gear or anything you do out there, get premium protection where it matters most.

How to Wear It

Wear your PolarJock® on its own as your only base layer bottom. Or, wear it under wind briefs, wind boxers, or long underwear for extra protection when and where you need it. Now dial in your layers to your activity and the conditions.

Winter Fat Biking in the Yukon, Canada.
Wore it in the February 2024 100-mile
Yukon Arctic Ultra. A key piece of equipment.
Fit and comfort was excellent.

Scott H. — Yukon, Canada

Super warm, comfortable and lightweight
for skiing and running. It cuts the wind without having to wear so many layers. And, it has
protected me from frostbite more than once!
