From Forest City Supply in Cleveland, Ohio, comes the authentic and complete 5-part U.S. Military issue Improved Modular Sleep System (IMSS) in the ACU / UCP digital camouflage pattern.

This is the genuine surplus system (NSN: 8465-01-547-2757) trusted by the U.S. Army to provide protection in climates ranging from temperate to extreme cold. The genius of the system is its layers, which can be used individually or combined to cover virtually any temperature.
