What Adventurers Say

I wore Frostdefender™ on a week-long snow trek and never felt the cold. The fit was perfect and the zip pockets were a lifesaver for my phone and keys.

Sarah M.
Alpine Guide, Colorado

These pants are a game changer for winter sports. The lightweight design doesn't bulk up my ski outfit and the warmth retention is outstanding.

Carlos R.
Pro Skier, Utah

My morning dog walks used to freeze me to the core, but not anymore. I can move freely and stay cozy even in -8°C temperatures.
