A bivy or bivouac sack is a sleeping bag with waterproof, windproof nylon covering. It can keep moisture and cold out even in snowy weather. It’s useful to hikers and climbers and for survival during natural disasters. Bivy sacks are made to withstand rough weather conditions, though some are more durable for repetitive use while others are suitable only for emergency situations. Bivy sacks tend to pack up small and weigh little for easy transport over long distances. All help keep your body heat in with some having body-heat reflection ratings between 70% and 90%. Not all bivy sacks can accommodate tall or large body sizes. Some come with extra survival tools like a compass or emergency whistle.
