What Is E.C.W.C.S?

ECWCS stands for Extended Cold Weather Clothing System, a layered clothing system originally developed by the U.S. Army to protect soldiers in extreme cold weather environments. ECWCS clothing and gear is designed to provide maximum warmth, moisture management, and versatility through a multi layered approach that adapts to varying temperatures and activity levels. The ECWCS system typically includes base layers, mid-layers for insulation, and outer layers that provide wind and water resistance. Rothco carries a wide selection of base layer underwear including our ECWCS Grid Fleece Shirt and ECWCS Silkweight Underwear. 

Rothco's ECWCS gear is not just for the military — it’s widely used by hunters, outdoor workers, survivalists, and cold-weather adventurers who need reliable protection in sub-zero temperatures.
