ECW Parka is a close copy of the current U.S. military PCU (Protective Combat Uniform) parka used by today's military service members. Evolved from the original ECWCS (Extended Cold Weather Clothing System) designs, the PCU lowers weight, increases packability, and greatly upgrades breathability and quick-drying capability. High-loft synthetic insulation provides similar thermal capabilities as natural down. This is the ultimate outer layer to take on the deep freeze, particularly in stationary positions like a deer stand.
