This listing for the INTERMEDIATE Bag only. For Matching Self Inflating Mat. The US Military Improved 5-Part ACU Digital Sleep System is a sleeping bag system constructed to insulate the user in environments ranging from mild weather to extremely cold weather. The system consists of two Mummy-style sleeping bags–the Patrol (Foliage) and the Intermediate Cold Weather (Urban Grey). Each are constructed of water-resistant, ripstop nylon. Each sleeping bag is fully functional independently. For a temperature 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 rated to provide 4 hours sleep at -40°F. This 5-part system includes a second smaller stuff sack. Non-flammable and machine washable. INTERMEDIATE COLD WEATHER BAG FEATURES. Water resistant, ripstop nylon. Free from cold spots. Insulation does not migrate in the bag. Anatomically designed foot box contains twice the insulation as the bag. Sewn-in, quilted chest collar prevents air drafts up and down through the hood. Hood adjusts for heat retention; includes nylon draw cord and barrel lock. Thanks for one of my local buyers for the review.
