Product Description

Engineered for the harshest environments, the Tennier Industries Inc. Modular Sleeping System is the genuine standard-issue gear trusted by the U.S. Army. Designed to adapt to fluctuating temperatures, this 4-piece system offers superior versatility and protection, keeping you warm from mild weather down to extreme cold conditions of -50°F when fully configured. Whether you are camping in the fall or trekking through sub-zero winter terrain, this system eliminates the need for multiple separate sleeping bags.

Modular 4-Component System:
This complete kit includes four brand-new, essential items to create the ultimate sleep shelter:
1. Green Patrol Bag: Designed for temperatures down to +30°F. It serves as a lightweight standalone bag for milder climates.
2. Black Intermediate Cold Weather Bag: Rated for extreme cold down to -10°F. It can be used separately or nested inside the Patrol Bag.
3. Woodland Camo Bivy Cover: Constructed with durable, waterproof, and windproof 3-layer GORE-TEX fabric. This cover protects your sleeping bag from rain, snow, and wind while allowing vapor permeability to reduce condensation.
4. Compression Stuff Sack: Heavy-duty storage for easy transport and compact packing.

Extreme Cold Protection:
By combining the Patrol Bag, Intermediate Bag, and Gore-Tex Bivy Cover, the system achieves an official rating of -10°F. When used in conjunction with the Extended Cold Weather Clothing System (ECWCS) layers, this setup is proven to protect users in temperatures as low as -50°F. The bags are constructed from water-resistant rip-stop nylon that is machine washable and inherently non-flammable for safety.

Military-Grade Features & Design:
This sleep system is built with technical features to maximize thermal efficiency:
• Anatomical Footbox: Contains twice the insulation as the rest of the bag to prevent heat loss from your feet.
• Quilted Chest Collar: A sewn-in design prevents cold drafts from entering or warm air from escaping through the hood.
• Self-Repairing Zipper: The reversible double-pull slider allows top or bottom ventilation and features a non-locking design that self-repairs if jammed.
• Anti-Migration Insulation: Snaps are strategically placed to prevent the insulation from shifting and creating cold spots.

Prepare for your next outdoor adventure with the same durability and reliability required by the U.S. Military.
