Product is so easily packable & lightweight to carry for emergencies or lightweight outings! The biggest downfall in my opinion is that this design doesn't work well for ventilation, especially if it is being used in colder conditions where keeping heat in is crucial. Bivy does not come with any stakes or flys to keep it taught through the night. First time I used it the bivy sort of drooped on my face all night & was fortunate it was warm enough at 10.5k ft in elevation to keep my head exposed with a mummy bag. It seems there's an updated version that may be better designed for this, would much rather opt for that option

Great Bivy For Grand Canyon Rafting Trip

work great for 4 day /3 night Grand Canyon rafting trip

Spacey

I was skeptical at first but then I set it up in the park. Plenty of space

Light Weight Bivy

Light weight easy to find color, enjoying my Bivy. The material is light weight so depending on what you are looking for, some might think this is a little ‘wimpy’ but it is fine for my needs. It will have slight condensation inside, I have tried a variety of bivies and cannot find a way to avoid this. At least everything about this Bivy dries out fast!

Or - Helium Bivy

I used this in the Adirondack High Peaks Wilderness in below-freezing weather with about 30mph winds. It did a great job blocking the wind and keeping out a lot of the chill. As long as you have the correct sleeping bag inside, this bivy will do the job. It's durable and spacious. It fit me no problem and I'm 5'9 ~270lbs. I still had room inside as well. It's also very lightweight and compact. My only complaint is that it doesn't open from the side, so I had to shimmy in and out through the top in freezing weather. This isn't fun as a bigger guy. If you're NOT overweight like me, this shouldn't be too much of a problem.
