The Extended Cold Weather Clothing System (ECWCS) base layers are designed for use in moderate to cold and wet conditions. Each piece can be worn by itself or in layers. Layering provides the flexibility of adjusting to temperatures ranging from 40 degrees Fahrenheit to minus 60 degrees. 

At McGuire Army Navy we carry US Army Genuine Military Issue GEN 1, GEN II and GEN III ECWCS products. 

Choose from a Level 1 light-weight undershirt to a Level 7 Primaloft Parka, or something in between. There are a variety of options to accommodate all environments.
