Recent Bivy Sack Reviews

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

Outdoor Research Alpine Bivy

rated 3.5 of 5 stars Works well in the summer, but a lot of condensation in cold weather. I switched to this bivy from an MSR tent to save weight. During the summer and warmer months it works great. Two complaints. For the high cost, OR could have included a way to keep the hood open while using the bug net. Also, during cold and damp weather, condensation builds up greatly. I spent a very cold and wet night last fall and learned to bring a tent in cold weather. Full review

Titanium Goat Ptarmigan

rated 4.5 of 5 stars The best of sleeping under the stars and being in a shelter. The bottom and sides are made of of 30D sil-nylon that is waterproof. The top is made of 15D breathable water resistant fabric. There is an option to add a bug net hood over the face with a separate zipper. The bivy sack comes with a stuff sack and together they weigh 6.6 ounces, or 7.6 with the optional bug net hood. If there is a threat of protracted rain I'll set up a DIY tarp to protect me and my pack, otherwise in good weather I use… Full review

Exped Bivybag VentAir/PU

rated 3 of 5 stars If you plan on sleeping in hot weather get something that keeps the fabric off your body and allows for windflow/airflow. I don't like the flexible wire, cannot seem to get the hood to stay off my face, it doesn't breathe as well as what I had hoped, but is it the most breathable bivy bag available (40000MVTR—found this out by emailing staff in America). I don't like it because I don't like fabric touching my face in general, not only that, but the fabric has to be super breathable and super air… Full review

TAS Auscam Bivvy Bag

rated 1 of 5 stars Bought this bag thinking it would be good, but 5000MVTR is not good enough for temps above 10c or 19c. This bivy is not breathable above or near 25°c, which is not good if you're living in a tropical/mediterranean environment with temps of 27°c and humidity 40%. As soon as I entered, the cool air inside the bivy changed to hot air as it made contact with my warm body. The hot air evaporated moisture/sweat from my body, but stopped when humidity/moisture in the bivy reached 90%. This made me feel… Full review

Equinox Sprawler Ultralite Bivi

rated 4 of 5 stars A well-made (in the USA), breathable bivy with a waterproof bottom. This is my first bivy and it went with me on my first tarp trip.  I squeezed in a four-day trip on the Ice Age Trail in mid-November, just before deer season. Trying tarp camping for the first time I ordered this a week before leaving and it was at my door with days to spare. Temperatures dipped to 37 and the woods were damp from earlier rain. The first two nights I pitched the tarp with the sides pegged to the ground. I was amazed… Full review
