The Gore-Tex Bivy Cover is an authentic, heavy-duty outer shell for sleeping bags, designed as an essential component of the legendary US Army Modular Sleep System (MSS). Built to rigorous military specifications, it provides ultimate protection against heavy rain, snow, wind, and dirt.
This is indispensable gear for active-duty military personnel, hikers, hunters, mountaineers, and outdoor enthusiasts who camp in extreme weather conditions year-round.
The Gore-Tex Advantage: Waterproof & Breathable
Constructed from durable Oxford-weave nylon and integrated with a high-performance, 3-layer Gore-Tex membrane.
-
100% Waterproof & Windproof: Completely blocks heavy downpours, wet snow, and ground moisture.
-
Highly Breathable: Allows body heat and sweat vapor to escape from the inside. This prevents condensation buildup, keeping your sleeping bag dry, warm, and safe from sub-zero drafts.
Versatility & Multi-Season Use
Thanks to its functional design, the bivy cover adds an extra layer of thermal insulation and doubles as a minimalist, one-man shelter (allowing you to sleep directly on the ground without a tent). Adapt it to any season:
-
Summer: Use alone or combine with a lightweight summer sleeping bag.
-
Shoulder Seasons: Pair with a patrol sleeping bag and thermal base layers.
-
Extreme Winter: Layer over both MSS sleeping bags for maximum warmth in freezing temperatures.
Key Features & Built-In Conveniences:
-
Heavy-Duty Hardware: Equipped with a rugged, full-length side zipper for quick and easy entry/exit.
-
Storm-Proof Closure: The zipper is protected by a wide outer storm flap with snap fasteners, blocking out driving rain and cold wind.
-
Adjustable Hood: Features an adjustable drawcord with a cord lock and an additional Velcro tab, allowing you to seal the hood tightly to trap body heat and prevent drafts.
-
Military Issue Reliability: Authentic US military markings (NSN) guarantee the highest standards of durability, wear resistance, and performance in tactical environments or long-term wilderness survival.
