U.S. Military Improved Modular Sleep System (IMSS) | 5-Part UCP Set

 

Prepare for any environment with the complete, genuine U.S. Military Improved Modular Sleep System (IMSS). Sourced by Forest City Supply, this is the authentic 5-part set (System NSN: 8465-01-547-2757) trusted by the U.S. Army to provide comfort and protection in temperatures ranging from warm summer nights to extreme arctic cold.

The genius of the MSS lies in its layers. By using the components separately or combining them, you can create the perfect sleep system for any condition. Use the green Patrol Bag for cool nights, the black Intermediate Bag for serious cold, or snap them both together inside the waterproof GORE-TEX bivy cover for a system rated to protect you in sub-zero temperatures. This isn't just a sleeping bag; it's a comprehensive, all-weather shelter solution.

Whether you're a year-round camper, a serious backpacker, or a prepper building a reliable bug-out kit, this is the ultimate sleep system. Stop buying a new sleeping bag for every season and invest in the one system that does it all.
