Bivy Sack Buyer’s Guide

Minimalist campers who don’t want a tent to interrupt their experience of the great outdoors should opt for a bivy sack. While these were originally used by climbers and mountaineers, where participants needed as little weight as possible, and bivy sacks have now evolved into breathable sleeping bag covers that are loved by hardcore campers who don’t want the weight of a tent in their bag.

Bivy sacks are also fantastic in emergencies, and anyone camping in extreme climates or out in remote locations should have one on their kit list. Or, if you’re camping in a tent in winter, they can be used as an added layer of warmth on top of your sleeping bag.

Not sure what bivy sack to go for? This buyer’s guide will tell you all you need to know.

Lightweight

Bivy sacks like the Tact Bivy Compact Sleeping Bag are designed to be extremely lightweight, often weighing just a couple of lbs. The best lightweight bivy sack will also be very portable, so you won’t be weighed down while on the move.

Compact

Bivy sacks like S.O.L Reflective Escape Bivvy are designed to be compact, usually fitting into the palm of your hand when inside their stuff sack. Of course, this gives them a huge advantage over tents, and make them great for cyclists, climbers or minimalists who don’t want to carry a lot of gear.

Material

Bivy sacks are usually made from a few different materials. Modern bivy sacks have a bottom tier which consists of durable nylon with a waterproof coating. The top tier is usually made from a lighter fabric and will be both waterproof and breathable.

If you’re camping in colder weather, look for a bivy sack with a reflective interior which will help to maintain your body heat and keep warm air in. Bivy sacks designed for hotter weather are usually more breathable and come with a built in mosquito net just like the Snugpak Jungle Bag Bivy Sack.

Durability

Durability is essential, especially if you are camping on rougher terrain. Look for a bivy sack made from durable and tear resistant fabric. Pre taped seams will add to the durability.

Waterproofing

All bivy sacks will be fully waterproof, but some may perform better than others in heavier rain. A waterproof but breathable top is essential. Go for a bivy sack with a waterproof coating and pre taped seams.

Heat Retention

Getting too hot or too cold are common problems while camping, especially if you’re using a bivy sack and no tent. If you’re camping in warm weather, look for one with mesh panels for better ventilation, and the fabric used should be very breathable. Internal side zippers will allow you to pull open the bivy sack if you are too warm.

Bivy sacks like Go Time Gear Life Bivy come with reflective interior that will keep you warm in colder weather. It’s important that the sack is still well ventilated. Look for one with vents, multiple zippers and a large head opening (with a drawstring that can be pulled tightly if needed).

FAQ

What is a bivy sack used for?

Bivy sacks or shelters are used as a lightweight and minimalist alternative to tents. They originally served climbers and mountaineers, but more recently are used for hardcore campers or those looking for an extra layer of warmth inside their tent. Minimalist campers will usually put their sleeping bag and sleeping mat inside their bivy sack and sleep in the great outdoors.

Bivy shelters are more tent-like, with an expanded headspace area as well as a full enclosure to block out the bad weather. Bivy shelters will feel a little more like a tent – and less like an extra sleeping bag!

Tempted to invest in a bivy sack for your next camping trip? These pieces of kit are perfect for minimalist campers who want to push themselves out of their comfort zone.
