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!
