MSS 5 Part Sleep System

1. Patrol Bag (Foliage Green)

The "lightweight" layer of the system. This bag is designed for temperatures between 35°F and 50°F.

• Best For: Summer and early fall camping.
• Key Features: Water-resistant ripstop nylon, an adjustable hood, and a reversible double-pull zipper that allows for ventilation at the top or bottom.

2. The Intermediate Cold Weather Bag (Urban Grey)

The heavy hitter. On its own, this bag is rated for temperatures from -10°F to 35°F.

• Best For: Deep autumn and winter conditions.
• Key Features: Thicker insulation and an "anatomically designed" foot box that provides extra room for your feet (or for storing your boots inside so they don't freeze). It features a quilted chest collar to prevent heat loss.

3. Large Compression Stuff Sack

The "command center" for your gear. This heavy-duty black nylon sack features nine adjustable straps (lengthwise and widthwise).

• Function: It is designed to house the entire 5-part system, compressing the bulk down to about one cubic foot for easy attachment to a rucksack or backpack.

4. Small Compression Stuff Sack

A more compact version of the large sack.

• Function: This is specifically sized to carry either the Patrol Bag or the Intermediate Bag individually. It allows you to save space when you don’t need the full system for a specific trip.

5. Multicam Bivy Cover

Gold Standard in Tactical Weather Protection

The Multicam Bivy Cover is the ultimate lightweight solution for the minimalist outdoorsman. Designed as the outer protective shell for the U.S. Military's advanced sleep system, this bivy uses a high-performance 3-layer waterproof laminate that keeps you dry. Whether you are "cowboy camping" under the stars or hunkered down in a storm, this shell provides a windproof and waterproof barrier that turns any sleeping bag into a self-contained shelter.

•  100 percent water/wind proof outer layer. Designed to enclose patrol and intermediate cold weather sleeping bag for the complete modular sleep system.
• Machine washable.
• Can be used alone for warmer temperatures.
• Approximately 80" x 30"

Why Buy the Complete System:

The magic of the MSS is its modularity. The bags are designed to snap together using heavy-duty non-locking snaps. By nesting the Patrol Bag inside the Intermediate Bag and sliding both into the Bivy Cover, you create a layered insulation system that traps air and manages moisture like no single sleeping bag can.
