The outer layer is a warm, comfortable fire-resistant Nomex® stretch-fleece sock made from Massif Flamestretch™ fabric.
The liner is an extremely high-quality merino wool sock from Smartwool. This liner sock is extremely comfortable, non-itchy, and wicks moisture from the feet into the outer layer to help prevent blisters and soggy feet.
This two-part system keeps toes comfortable, dry, toasty, and protected!
Flamestretch fabric passes stringent ASTM D 6413 Standard for
flame resistance. |
