We've been big believers in the benefits of bivy sacks for a long time, and a group of dedicated Outdoor Research employees took our bivies out on bike camping, backpacking, and alpine climbing trips to see if they lived up to their reputation. The results were unanimous: Every one of us believes that bivy sacks are the most comfortable, easy and social way to sleep outside. So we broke it down for you. Here are our top 10 reasons why we prefer bivies over tents, and why youโll want to consider switching up your camp style, too.
1) Spend less time setting up camp, and more time enjoying the view.
If youโre trying to cover a lot of miles, and planning long alpine-start-style days, a bivy lets you fully maximize your time on the trail. Theyโre easier and faster to set up after dark, as well as packing up before the sun rises, leaving you with even more daylight to enjoy your time out there.
2) Sleep virtually anywhere.
The most delightful thing about a smaller shelter footprint is the opportunity to camp where no tent could ever dream of fitting. Perched on the edge of a vertical cliff, sure... but more likely, at a popular campground on a sunny weekend, when the only sites left are too small for a tent. Or, when youโre a party of four but a pair of two-person tents canโt fit side-to-side. Save roomโbring a bivy instead.


3) Itโs the ideal solo shelter.
Why pack an entire tent on a solo trip? If you can afford to save the pounds, ditch the heavy and bulky set up for a lightweight one-person bivy.
4) Itโs also regarded as โthe social shelter.โ
If there are more than two people on your trip, chances are the moment you set up camp, each pair will retreat to their own tent, unlikely to be seen again until the morning. But with bivies, the partyโs just begun once you get to camp.
By sleeping in bivy sacksโeven if they're spaced six feet apartโyou can enjoy the time with your friends without each person zipping up and zoning out into their own tent.
5) No more disturbing your partnerโs sleep.
If kicking, snoring, and rolling over onto each other is a common occurrence in your tent, you should think about giving yourself some extra space. Bivies may pack small, but they have ample room inside to move around, stretch out, and even store gear.
6) Save weight and space for the fun stuff.
Streamlined bivies are ideal for adventurers looking to shed ounces and maximize performance on the trail. Whether that means going lighter to move faster over the milesโor to leave more room for whatever floats your boat out on the trail. Beer, donuts, books, whatever.
7) Waterproof protection without the stuffiness.
If your experience of sleeping in a bivy is akin to an oversized plastic bag, youโre choosing the wrong bivy. The beauty of the technology found in our bivy collection is that itโs just as breathable as it is waterproof. No stuffy condensation buildup, and no weather leaking its way in. Itโs that simple.
8) Stargaze from the comfort of your shelter โ without worrying about bugs.
Most of our bivy sacks feature an enlarged head space with a mesh screen to keep out bugs without sacrificing views of the Milky Way. If the weatherโs nice, leave the outer layer open for star views. If it starts to deteriorate during the night, a quick zip will leave you securely sheltered from the elements. No need to scramble around to add a tent fly!
9) Bivies are more reliable in bad weather or emergency situations.
A lot of things can go wrong with a tent; like a broken pole or malfunctioning zipper. If a tent canโt stand up or keep out weather, itโs lost its purpose, which is especially dangerous in flash storms or dangerously cold temps.
On the other hand, since bivies only have one entry and exit point and donโt rely on poles to function, theyโre more likely to withstand those bad situations. And if youโre looking for something designed entirely for the โworst case scenario,โ youโll want to check out the Helium Emergency Bivy.
10) Breakfast in bed.
Nothing quite beats slowly waking to sunrise, sitting up in your bivy, and firing up the stove without leaving your sleeping bag. In fact, you can perform most of your camp chores from the comfort of your shelter.
We promise that once you try a bivy out in the backcountry, youโll never go back to a restrictive, cumbersome tent. Check out our best selling Helium Bivy, our most breathable bivy the Alpine AscentShell Bivy, and our full collection of Bivy Sacks to see how you can upgrade your camp set up today.
