Soft Shell Cold Weather Trousers

Shell Layer: Designed to be worn with base and insulative levels for use in moderate to cold conditions. Note: This item is roughly equivalent to the Gen 2 ECWCS trousers.

The GEN III ECWCS Soft Shell Cold Weather Trousers are designed for use in cold weather conditions as a soft shell layer combined with other base and insulative layers.  Constructed with water resistant materials the Level V Soft Shell Trousers provide light weight, low bulk and extreme comfort for movement. When combined with base and insulative layers this level serves as an excellent outer shell in moderate to cold environments.

The Level V trousers feature a zippered fly opening as well as two front and side pockets with Velcro fastener openings. The elastic waist has belt loops and provisions for suspenders as well as side-zipper openings for ease of donning over other layers. The leg openings feature a calf-high side-zipper and an elastic cuff. All zippers have a thong for ease of opening and closing when wearing gloves.
