Whether you're a pro backpacker or are just starting to take up camping, a bivy sack can be useful for many reasons. For minimalist backpackers, the ultralight, pole-less tents are a great way to cut weight in your pack and connect with nature. On the other hand, a bivy sack can also act as a comfortable blanket for those spending a night or two outdoors, in a tent, or in a cabin. Plus, they can also be great in emergency situations when mother nature strikes. Whatever your intended use, sleep in one of our favorite bivy sacks to stay warm and dry the next time you go on an outdoor adventure.
