Carefully designed in conjunction with the United States Marine Corps. This cutting-edge sleep system is expertly crafted with the highest quality materials inside and out. Each system includes the highly desirable USMC 3 season sleeping bag, USMC Improved Bivy Cover, and USMC SealLine waterproof compression stuff sack. The 3 season sleeping bag features a water-repellent nylon ripstop shell, polyester fill, draft baffle, and anti-microbial inner liner. There is more than enough room to add a sleeping pad. The bivy cover is made of 100% Nylon and 100% PTFE (Gortex) and features mesh bug screen. We completed this system with a genuine USMC issue SealLine waterproof compression dry bag for convenient, compact waterproof transport. Rated down to 20 degrees with proper clothing. When packed up and compressed in the dry bag, system measures 9’’ in diameter, 12’’ high and weighs 4.75lbs. The system is in used condition and will show signs of use or prior repairs but will be perfectly functional for many years of use. Color: Coyote. Genuine U.S. Military Surplus. MADE IN USA.
