Our Bivy Buying Guide

Originally developed as a one-person shelter to protect mountaineers and climbers from rain and snow during multi-day ascents, the bivouac sack — or bivy sack — now has a wider range of uses. A traditional bivy sack, made from a waterproof, tear-resistant fabric, performs two basic functions: to increase the user’s body temperate and keep them dry.

Bivies — reminiscent of an ultra-lightweight sleeping bag or extra-large rain jacket shell — have all have a built-in head opening and come with features like draw strings around the head opening to seal out moisture, full-length zippers and factory-sealed seams for extra warmth. The outer shell of the sacks are available in many different colors, including bright, attention-grabbing hues like red and yellow to improve the user’s visibility to rescue crews.

The products, which are stored in a compact bag, are ideal for emergency preparedness, backcountry excursions, long-distance biking trips, train running and winter camping. The primitive shelters are ideal for sleeping in technical terrain, where ledges are too cramped for a tent, but can also be used as a poncho, blanket, sleeping bag liner, ground cover and more. Some bivy sacks are also equipped with a whistle and a nylon core draw string that can used to secure or repair gear, making those options great for emergency situations. Because bivies can be reused, easily stored and often weigh just a few ounces, they’re convenient for travel and outdoor adventure.

What’s the difference between a bivy sack and a bivy shelter? The latter is a low-rise tent that includes mesh panels attached to the head opening or hoops to keep the fabric off your face (think: a fancy bivy sack).

DWYM Fun Fact

  • The definition of a bivouac is a temporary encampment under little or no shelter.
  • While tents date as far back as 40,000 B.C., the recreational tent wasn’t popularized in the United States until the first half of the 20th century, when Americans had more resources and leisure time to spend outdoors after the Industrial Revolution.

The Bivy Tips and Advice

  • Depending on the product, bivy sacks are designed to help users retain up to 90% of their body heat.
  • If you’re a tent camper who wants to downsize to a no-fuss shelter, a bivy sack could be the answer; since they require no setup, pitching or breakdown, they’re great for adventurers who want to maximize their time with a fast overnight.
  • Bivies are great alternatives to a tents in warmer temperatures (for example, above 50).
  • If you plan to use your bivy sack for camping, increase your comfort by: placing a bottle filled with hot water in the core zone (your crotch or arm pit area) for extra warmth, use a sleeping pad underneath for extra cushion and pull the drawstring around the opening snugly around your head to avoid breathing into the bivy and to seal out moisture.
