The U.S. Army-Enhanced ACU Modular Sleep System (MSS) is a sleeping bag system designed to insulate the user in environments ranging from mild to extremely cold weather. The system consists of two mummy-style sleeping bags: the Patrol (Foliage) and the Intermediate Cold Weather (Urban Grey). Each is made from water-resistant ripstop nylon. Each sleeping bag is fully functional independently. For temperatures down to -30°, insert the Intermediate Cold Weather bag inside the Patrol bag. Each bag is compatible with the vapor permeable Bivy cover. When all 3 components are used together, the system is designed to provide 4 hours of sleep at -40°F. Non-flammable and machine washable. Made in the USA by Tennier Industries.
