With many military surplus items, you also might need a crash course in etymology.

Coming from the German Swiss term Beiwacht (bei by, and wacht watch or patrol) the proper term for this item is is biv·ou·ac (/ˈbivo͞oˌak/) but most know it as the Bivy. When inclement weather catches you off guard, or your quick stay in the woods doesn't require a tent, the Bivy fills in the gap as a quick-to-deploy rudimentary shelter. 

Part of the Modular Sleep System (MSS), the bivy cover is a way to turn your sleeping bag into a quick shelter that will keep you warm & dry without a tent. Providing a barrier against wind chill or rain, it's an extra 5-10 degrees of insulation you'll be thankful for. Unlike the rest of the system, it's also covered in a proper camouflage to enable troops to have a low-vis sleep in enemy territory where a tent might give them away. 

Simply slide your MSS Patrol Bag, Intermediate bag, or other sleeping bag inside (MSS bags can be physically attached to the bivy for convenience) and you have a mostly weatherproof cover in a pinch.

What makes these bivy covers special is that they are vapor permeable. In layman's terms, old waterproofing fabrics trapped humidity and moisture inside as well as keeping them out, so modern materials like Gore-Tex actually have breathability to allow for less condensation. This is crucial for avoiding Hypoxia, or lack of oxygen inside of a sealed shelter, and is a game-changer for wet & snowy climates where a Bivy may be necessary.

Perfect Bivy Bag

Condition was described as excellent, but 'flawless' would have been more accurate. Thanks, guys.

Sleeping warm

As I get more into winter camping/hiking again, I need new winter gear. Komando has been and still is my go-to store. Enter every raffle, get gift cards and buy gear, enter the next raffle…….

Looking forward to using this bivy with the shelter half I also bought (with my raffle winnings)

It rolls up nicely, I’ll probably figure out how to get it smaller when I add it to my pack, as I didn’t try to roll it very tight
