The 7 Best Bivy Sack Reviews (In 2019)

Mountaineers and backpackers have long been on a quest to find a sleeping tent that is compact, compresses tightly, and is lightweight to carry. The best solution for some is a bivy sack. Original bivy sacks started as waterproof sleeping bags that provided temporary emergency shelter and sleeping space for adventure-seekers. Today’s bivy sacks reflect body heat to protect the body from the elements longer than laying on the ground out in the open. They have the added benefit of being fully sealed to keep out bugs, snakes, and other animals.

Bivy Sack vs. Sleeping Bag

Backpacking sleeping bags have many purposes. Kids’ sleeping bags are a “must-have” for families with children. Kids’ sleeping bags are lightweight, colorful, and may reflect a child’s favorite characters or celebrities, but they are intended for indoor use. Heavier sleeping bags work best for tent or RV camping to help keep them warm and dry, regardless of the weather.

Bivy sacks were designed for a greater purpose. The idea behind a bivy sack is to fully enclose the body to protect it from the weather and anything else in the wilderness that will bother you while you are sleeping. Mountain climbers, backpackers, and other extreme athletes can’t be unnecessarily bogged down by extra size and weight in the back pack.

Their sleeping system needs to store as tightly and as compactly as possible, while being lightweight. The down side to bivy sacks is that they are confining and not as comfortable, so look at this article for the best sleeping pads to complement them. A one-person dome tent may be a better choice for someone who is claustrophobic.
