The Ultimate Waterproof Shield for Your Sleep System
When the weather turns hostile, your sleeping bag's performance can mean the difference between a restful night and a miserable one. The USGI ACU GORE-TEX® Bivy Cover is an authentic piece of military surplus designed to be the impenetrable outer shell of the military’s Modular Sleep System (MSS).
Constructed in the USA using 3-layer GORE-TEX® laminate, this bivy sack is 100% waterproof, windproof, and highly breathable. Whether you are a backpacker, hunter, survivalist, or tactical professional, this bivy cover prevents rain, snow, and morning dew from soaking your gear, while allowing internal condensation to escape.
Available now at Fury28.com, this genuine issue bivy cover can be used as a standalone ultralight shelter in warm, wet weather or combined with a patrol and intermediate sleeping bag for sub-zero winter expeditions.
