Top 5 Best Bivy Sacks on the Market right now – 2019

Bivy sack is a short abbreviation used for “bivouac sack.” It is basically a waterproof shelter designed for a single person. These sacks are for people who frequently travel solo in the backcountry and desire to shed every possible ounce from their loads. As compared to tents, they are very small and lightweight.

The main problem with these sacks uses to be the humidity that condenses on the inner side. But with time, bivy sacks have evolved a lot to include waterproof breathable fabrics to help reduce internal condensation.

With hooped tent poles you can always convert bivy sacks to bivy shelters. Bivy sacks provide more warmth as your body heat is retained inside. Thus, they can be adapted for warm or cold weather.

As bivy sack is so confined, breathability will be extremely important. Thus, selection of appropriate material is a must. Bivy design today involves 2 tiers of fabric; the top tier is usually a lighter fabric made of ripstop nylon and treated with a waterproof, breathable laminate and the bottom tier generally consisting of a sturdy and durable urethane-coated nylon.
