Bivy Sack – Best Lightweight Shelter

5 Star Emergency Medical Supplies recommends the best lightweight bivy sack shelter  (also known as a bivouac sack, bivvy bag, bivi bag, bivy shelter or just bivy). It is a lightweight, waterproof shelter, and an alternative to traditional tent systems. It is used by climbers, mountaineers, hikers, ultralight backpackers, soldiers and minimalist campers. Our supplier, the Survival Camping Store offers a wide range of the bivy sacks.

Bivy Sack Shelter Protects User from Weather

A bivy sack at its barest is a thin waterproof fabric shell (for example, made from lightweight Best Lightweight Bivy Sack Shelter - Sacksilnylon) designed to slip over a sleeping bag, providing an additional 5 to 10 °F (2 to 5 °C) of insulation and forming an effective barrier against wind chill and rain. A drawback of a simple bivy sack is the humidity that condenses on the inner side leaving the occupant or the sleeping bag moist. This problem has been alleviated somewhat in recent years with the advent of waterproof/breathable, such as Gore-Tex, which allow some humidity to pass through the fabric while blocking most external water. Another solution is the use of an inner vapor barrier liner bag, for example a  silnylon sack, to prevent body moisture from entering and condensing in the sleeping bag.

A traditional bivy sack typically cinches all the way down to the user’s face. It leaves only a small hole to breathe or look through. More recent developments in high-tech breathable fabrics have resulted in the creation of Gore-Tex Exchange Lite. this is an air permeable version of the fabric. It can be safely zipped up around the user’s head in order to shut out the elements completely. The fabric not only allows moisture to escape, but also the carbon dioxide exhaled by the user.

Bivy Sack Serves as Compact Emergency Shelter

The Survival Camping Store also provides a bivy shelter. It is a compromise between a bivy sack and a single-person tent.

Many campers gladly accept the increased carrying weight of a bivy shelter for the perceived increase in comfort. The traditional bivy sack still holds its place among mountain climbers and backpackers. It is frequently carried as a compact emergency shelter on long or dangerous hiking or hill walking expeditions and high mountain climbs.

Our bivy shelter is sufficiently taut to keep the fabric off the occupant inside to prevent condensation from soaking the bedding and provides some additional breathing room around the head.

Bivy Shelter Popularity

In the UK, for example, bivy shelters have become very popular among fisherman, who, in pursuit of their quarry, fish throughout the night. This upsurge in popularity has increased competition among manufacturers and designs have become more advanced.

About 5 Star Emergency Medical Supplies


  1. I watched sotihmeng similar with my first hurricane, except they went in a row like dominos, and we could hear the explosions. Now I live on a dead-end, so when our transformer was struck, it didn’t travel down the line, since ours was the last one. Took a few days for them to replace that single transformer, and it wasn’t even a tropical storm!Well, I used to play online board games, and found out my opponent lived in Florida this was a few months after their busy 2004 hurricane season. I asked her how long she was without power, and she said she only had a few flickers, but then the power stayed. I asked how far inland she lived, and although she was somewhat inland, other neighboring towns were without power after hurricanes passed over.So how come she didn’t lose power? Because the developers of her tiny neighborhood had the power lines placed UNDERGROUND! I forget where I read it, but before our most recent hurricane, I read of some theories or maybe studies about how if power companies would turn off power when the weather got really bad, the theory was that there’d be less damage to the grid afterward. I believe I read that it was discussed before our recent hurricane, but they caved, because they worried about complaints and massive phone calls. Well sorry, you’re most likely going to lose power in a hurricane anyway, so until we have power lines underground, turn off power when weather goes bad to decrease grid damage. It took almost 3-4 weeks to get everyone’s power back on after Ike, and more than a month after Rita side-swiped the area to my NE.I have no idea if underground powerlines would be safe from solar storms though.

    • There are several merchants for which I have posts that you should review to look at alternatives to electricity during a disaster should we have no power.
