Outdoor Research Alpine Bivy

rated 4 of 5 stars This is my first bivy sac. I wanted to try one for its compact size and as a backcountry shelter. After much research I settled on the OR Alpine Bivy. I used it recently for a two-night outing and so far I’m very pleased. I would recommend taking the time to stake it down. Earlier this fall I slept in the Alpine Bivy for two consecutive nights on the Atlantic Coast in Newfoundland. The first evening was beautiful, about 5deg Celsius. I slept with the cover open and watched the stars through the… Full review

Outdoor Research Helium Bivy

rated 5 of 5 stars Needing to minimize backpack weight is no reason to miss out on overnight winter adventures. A quality bivy will do the job nicely, without adding significantly to a backpack burden. Shelter can be important, especially in winter. The breathable, water-resistant OR Helium Bivy includes a bug net for summer, generous headroom (secured by a nested carbon-fiber hoop), and five points of suspension to secure it against high winds if you need to exit during the night. Accumulating outside snow can be… Full review

Slumberjack Contour Bivy

rated 4.5 of 5 stars First shelter I carry for survival. I purchased my first Slumberjack Contour bivy in 2010 on the advice of my son. I carried it on a motorcycle trip that started in Death Valley where I survived a 50-mile-an-hour sandstorm. Later on that same trip while in Zion during flash floods it saved me from torrential rains. While in Bryce during a snowfall of two feet it kept me warm, maybe up to 10° difference, while my three-season tent protected me from the snow. I'm sorry it only lasted eight years. Full review

Outdoor Research Helium Bivy

rated 4 of 5 stars Spacious lightweight bivy, waterproof, and breathable with minimal condensation issues. I have spent almost two weeks in the Outdoor Research Helium Bivy and found it to be pretty acceptable for my use. I bought it from Massdrop for $148.07, and when received, tried it out on my back lawn without turning off the early morning sprinklers. I slept comfortably all night and did not get wet from the sprinklers, which were on for 20 minutes.  More recently, I took the bivy on an almost two-week trip… Full review

Outdoor Research Advanced Bivy

rated 5 of 5 stars Great bivy sack! I own the OR Advanced Bivy, which I purchased at REI in 2003. I LOVE it!  It came with me on a four-week backpack of the Hotsprings Trail in Central Idaho (Frank Church River of No Return Wilderness). On this trip, I used it inside the REI Quarter Dome for a few more degrees of temperature warmth, and rolled the whole shebang up (plain blue foam sleep pad, 0 degree bag, bivy), and strapped it to the bottom of the pack inside a black plastic bag. It really helped keep this girl… Full review

Sierra Designs Backcountry Bivy

rated 3.5 of 5 stars Great shape and design with functioning waterproof breathable (WPB) material, but just not enough of it. I bought the blue-yellow-black 2017 long sized model online, on sale for 35% off normal retail price. Overall, at that price point, I give this bivy a grade “good”, but NOT “very good”. Had I paid full retail price, I’d give it a lower grade due to top yellow patch not being breathable. The wet spot the yellow patch created on my bag was more noticeable, and took longer to dry than… Full review

Outdoor Research Advanced Bivy

rated 4 of 5 stars I used this very often for three years and then infrequently for the next eight years. It worked great. Bivy use has its pros and cons, but I will leave all that to the experts and just tell what I know about this product.  I used this with a poncho tarp as my primary shelter for three years of hard use. It was great. The only issue I had was condensation in temps below 20 F degrees in the Southeast. I took my Western Mountaineering Alpinlite down to 9 degrees with this bivy and, it was cold,… Full review

Borah Gear Dimma Bivy

rated 5 of 5 stars Light and well made bivy. This is the start of my review, which I will finish after I get back from the Smokies.   Update 12/2017: My Dimma Bivy performed as expected in the Smokies. It kept me dry and the nylon sides helped block the wind. The extra protection allowed me to raise the sides of my tarp and I had no condensation at all. It rained two of the three days we stayed out. The mesh strip down the middle helped ventilation, so there was not moisture buildup in the bivy. The temps were a… Full review

Borah Gear Side Zip Ultralight Bivy

rated 5 of 5 stars Never leave home without it. Most backpackers have a few extra pieces of gear. On one trip you might take a bigger or smaller backpack or a different tent/tarp depending on weather. Maybe a poncho one trip and a full rain suit another. But what gear goes on every trip? My Borah bivy is one of those!! I have the side zip extra wide bivy made out of very breathable argon90. The extra wide Borah bivy will hold me, my 30-degree ZPacks extra wide down sleeping bag, and my inflatable sleeping pad (I'm… Full review
