The PROPPER Gen II ECWCS Parka is authentic US Army outerwear that provides lightweight protection from the harshest elements. The ultralight, three-layer breathable GORE-TEX® barrier protects against water and wind, and is softer and quieter than the first generation design. It also allows sweat to escape without sacrificing protection from the elements. The Gen II is NIR-compliant and will remain waterproof even after repeat launderings and exposure to DEET, oil and other types of petroleum. All seams are sealed with GORE-TEX® to provide superior water protection throughout.
