USGI (MSS) Urban Gray Nylon Intermediate Cold Modular Sleeping Bag - Used

USGI Urban Gray Modular Sleep System (MSS) Intermediate Cold Weather Sleeping Bag - Used

The USGI Urban Gray Intermediate Cold Weather Sleeping Bag is the cold-climate thermal layer of the United States Armed Forces Modular Sleep System (MSS). Purpose-built for winter conditions and sub-freezing survival, this mummy-style sleeping bag is independently rated for temperatures ranging from 30°F down to -10°F (-1°C to -23°C). Designed for extreme adaptability, it can be deployed on its own during freezing weather or snapped directly together with the Lightweight Patrol Bag and Waterproof Gore-Tex Bivy Cover to form an extreme cold weather system capable of surviving temperatures down to -40°F.

Fabricated with a durable, water-resistant ripstop nylon shell and filled with high-loft synthetic insulation, this bag retains vital body heat even in damp or high-humidity field environments. Key features include an anatomically contoured footbox to accommodate boots, a non-locking full-length heavy-duty YKK dual zipper for instant "breakaway" emergency exits, an insulated chest baffle, and an adjustable drawcord hood to seal in warmth around the head.

In Used / Field-Serviceable condition, this military surplus sleeping bag is 100% operational, thoroughly cleaned, and structurally sound. Sourced directly from U.S. military turn-ins, expect authentic signs of field deployment—such as light fabric fading, minor cosmetic scuffs, or handwritten military identification marks on tag blocks. Every bag undergoes complete hand-inspection to verify that all heavy-duty snap fasteners hold firmly, the zipper tracks operate smoothly, and the insulation remains evenly lofted without major clumping, tears, or structural defects.
