Super lightweight and well designed, however, not very breathable and I personally find it slightly claustrophobic

Good Unless You Fully Zip

I’ve used this bivy a handful of times and I like it, but don’t love it. What I like. Comes with a pole to keep the netting off your face. To me it feels like I have good wiggle room (I’m 6ft and 175lbs). Love how compact and light it is. I haven’t tested it in the rain but it does say it’s waterproof. The only dislike I have, and it’s a big one. I have tried to sleep with the Bivy fully zipped up twice and both of those times I have woken up damp. I’m guessing this is from trapped condensation. Now when it’s only the bug net zipped up, I don’t have this problem. Going to test it out some more this summer and see if this is a constant problem.

The Best Light Weight Bivy Option

After having this bivy recommended to me, I've been exceedingly happy with it. It's very well built, easy to setup/take down and very small size/weight for your pack. If you are looking for something very compact and light weight, this is the BEST option for you.

Not Waterproof

Spent a night with heavy rain for 10 hours straight. After about 3 hours the fabric started to soak through. Should not be advertised as waterproof. If it’s not raining, this is a great lightweight option. I’ve used for bike packing in the desert and was pleased with quality. Would recommend sleeping with vent open, breathing becomes difficult went fully zipped up and condensation builds up. No ventilation. Im 6’4” and I fit with a backpack inside as well.

Odd Design

The way this bivy is designed makes it difficult for me to sleep in it. The mesh screen is positioned in a way that when you’re laying in the bivy you can’t see out of the mesh when you’re laying on your back. I wish they would’ve put the mesh directly over your face so that you could get fresh air and see out when you have the fly open. Otherwise it breathes well and is a high-quality bivy.

Used the bivy a couple times camping/backpacking since purchasing and will recommend that you leave the bug net unzipped slightly for ventilation since condensation build up can be an issue but overall really good deal on the product and really satisfied with its weight and overall size, I highly recommend it.

Excellent For Those Light Weight Over Nights

Light weight, easily packable. completely waterproof

Not Worth It Imo

I got this specifically for use in the PNW. I tried using it as a standalone product with out using guy lines, and as you can imagine, it doesn't really stay up on its own at all. It basically served as a bug net for me on Olympus. Which was great, but bug nets are way cheaper. I would be very nervous in heavy rain or snow that this wouldn't stay up at all or would fill with moisture inside from breathing. Pros are that it is very light and definitely better than nothing if you need shelter. If you can secure guy lines to the pole, I'm sure it is a better experience in general.

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.

Great gear for lightweight backpacking. Really comfortable and pleasant in nice weather.

Great For A Backup

This thing saved me when I thought I’d be sleeping in a Hammock but a cold front came through. Only issue I had was condensation build up. I wouldn’t use it as a primary but it was a handy backup.
