AirBoss Extreme Cold Weather Mukluk (ECWM)
The World’s No. 1 Extreme-Cold Boot System

Designed and developed in Canada after extensive field testing and user feedback, the ECWM achieves the optimal balance between weight, insulation, comfort, and durability. Breathable and anti-microbial, lightweight yet heavy duty, this is the world’s finest extreme cold weather mukluk.

Top Performer

Developed over the last decade for military use, the ECWM has been optimized based on feedback from extensive field testing by Canada’s Department of National Defense. It keeps feet dry and warm for up to eight hours at temperatures ranging from 0° C to −55°C.

Waterproof & Breathable

Lighter than competing products, the ECWM boot is fully waterproof yet remarkably breathable. Its moisture-wicking, anti-microbial inner felts hold the user’s foot securely with no undue friction or discomfort.

Chemical Resistant

The boot’s tough outer shell system resists chemicals such as degreasers, cleaning agents, and lubricating oils.

Compatibility

The ECWM boot offers extra ankle support and a flexible outsole that is compatible with military skis, crampons, and snowshoes.
