These U.S. Air Force Overpants are a component of the Air Force's APECS (All-Purpose Environmental Clothing System) for maintaining waterproof capability in the most hostile territory. GORE-TEX membrane stops moisture infiltration, while still allowing your skin to breathe naturally, even under high activity. Pass-through side pockets let you access your clothes underneath. Decked out in the Air Force (and Space Force!) camo of the future, OCP Multicam.
