MSS Patrol Sleeping Bag | Lightweight USGI Modular Sleep System Bag
The MSS Patrol Sleeping Bag is the lightweight sleeping bag component of the U.S. Army Modular Sleep System. It was built for temperate field conditions where the full sleep system is not needed. Use it alone in mild weather, or combine it with other MSS components when temperatures drop.
This genuine USGI Patrol Sleeping Bag is rated for 30°F to 50°F under military conditions. That rating needs real-world context. The 30°F rating is closer to a military survival threshold than a comfort rating. For most sleepers, the practical comfort floor is closer to 40°F. Cold sleepers should plan for 45°F to 50°F when using this bag alone.
Built for the Army Modular Sleep System
The Patrol Bag is designed to work as part of the full MSS Modular Sleep System. It can be used by itself during warmer nights. It can also snap into the MSS Intermediate Cold Weather Bag for deeper cold-weather protection.
When paired with the Intermediate Bag, the full system is rated down to -30°F under military conditions. Add the Gore-Tex Bivy Cover for wind and moisture protection. You can also shop the complete MSS bundle if you want all major components together.
Lightweight Synthetic Sleeping Bag for Field Use
The Army Patrol Sleeping Bag uses Polargard® HV synthetic insulation instead of down. That matters in the field. Down can collapse when soaked and lose much of its warmth. Synthetic insulation retains more warmth when damp and dries more predictably.
That makes this bag a smart choice for camping, hunting, training, truck kits, emergency gear, and military surplus sleep systems. It is light enough to carry on its own, yet rugged enough for real outdoor use.
The 1.9 oz water-resistant ripstop nylon shell helps shed light moisture. The oversized foot box improves comfort and ventilation. A draft flap helps reduce heat loss along the zipper, while the adjustable hood helps seal in warmth when the temperature drops.
Genuine Military Surplus Sleeping Bag
This military surplus sleeping bag is built for field reliability. It features a reversible double-pull YKK zipper that opens end to end and works from inside or outside the bag. Snap fasteners along the zipper run connect the Patrol Bag to other MSS components.
For best results, pair this bag with a quality sleeping pad. Ground conduction is one of the most overlooked causes of cold-weather discomfort. A Therm-A-Rest Self-Inflating Pad or similar insulated pad can make a major difference.
Made in the USA by Tennier Industries, this bag is a proven lightweight sleep system component for soldiers, veterans, campers, hunters, preppers, and outdoor professionals.
