When the temperatures drop, staying warm and comfortable is key — and the USAF F-1B Extreme Cold Weather Pants are up for the task. Designed for dry, cold environments, these trousers combine rugged durability with thoughtful features to keep you protected and cozy.

Design and Materials

These pants are built to handle serious cold. The outer shell is made of a durable cotton/nylon Oxford which stands up to tough conditions. Underneath, 100% polyester batting provides outstanding insulation, helping you stay warm even in sub-zero temperatures with a cotton lining on the inside.

Water Repellency

The F-1B trousers feature a water-repellent treatment that offers protection against snow and light moisture. While they can handle dry cold like a champ, they aren’t meant for wet conditions, so they’re best suited for environments where staying dry is part of the plan.
