The Active Crew is designed for the active hunter as its super silent, stretchy, and lightweight thanks to the ThermalFlex fabric. It acts as a base-layer with a brushed inner that is soft against the skin and insulates your body with a thin layer of warm air. The Active Crew can be worn alone or layered thanks to its smooth outer face which sits comfortably under midlayers. Crew neck style fits easily under layers without bulk.
