Why We Like The Helium Bivy
Tipping the scales at just barely over a pound, the Helium Bivy is what we grab to move fast through alpine terrain and wilderness expanses without excess weight slowing us down. The Helium Bivy offers total waterproofing and maximum breathability with its Pertex Shield+ 2.5-layer membrane, TPU floor lamination, and fully taped construction. Ultimately, this means you stay pleasantly dry when you're camping out in widely variable conditions, all without soaking in a sauna during humid summer months.

Review Summary
Customer Images
Here's what customers have to say
The lightweight and compact bivvy shelter is well-suited for ultralight activities, with users praising its small packed size and easy setup. However, some report issues with condensation buildup leading to a damp sleeping bag, especially in wetter conditions. The bivvy may also feel cramped, particularly when using a thicker sleeping pad. While suitable as an emergency shelter or for short trips, the product may not be ideal for longer excursions where staying dry is more critical.

It keeps me warm and it is super easy to pack up. With a light pack it is possible to fit a sleeping pad zero degree bag, and then my pack within the bivvy comfortably. The only hassle is getting in and out which just comes with practice.

Lightweight, but at a cost
I loved how small and compact the bivy was making it very easy to carry for extended trips. Fully compacted down, the bivy is about the size of a 40 oz nalgene and just as light as an empty one. My largest concern was the condensation build up. Using a down bag and then waking to find the whole inside of the bivy WET was rough (even with the bug net open). Now my bag was wet and had to cut my trip short so i wouldn't freeze.

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 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.

Cozy
I used this on a 268 mile 4 night bike packing trip through the Los Padres National Forest. It packs small and is light. It’s easy to set up and tear down making it great for a beginner or expert hiker or bike packer. The zipper is a little funky to use from the inside, especially if you only want the mesh closed. The foot area is a little narrow so stay away from wide sleeping pads. I’m 6’0” 190 lbs and fit with some room to spare but not much. If I used a foam pad that would give me more room than my current 3” air pad.
