Why We Like The Outdoor Research Helium Bivy

The Outdoor Research Helium Bivy is ideal for moving fast through alpine terrain and wilderness expanses without excess weight slowing us down. Don't let its minimalist design fool you into thinking it's lacking weatherproof performance or functional features. The Helium Bivy offers total waterproofing and maximum breathability with its Pertex Shield Diamond Fuse 2.5-layer membrane, TPU floor lamination, and fully taped construction. We stay pleasantly dry when we're camping out in widely variable conditions, all without soaking in a steam room of built-up perspiration during humid summer months.


The Helium features a clamshell design that promotes a restful night's sleep with a Delrin Single-Pole system acting as a stabilizing structure for the bivy itself. The hood unzips during pleasant weather for extra ventilation and impressive stargazing potential. No-See-Um mesh lining keeps biting insects from eating you alive when you're sleeping with the hood unzipped. Other key features include dedicated straps for attaching your sleeping pad, an internal mesh pocket, and stake-down points for securing this bivy in nasty weather.

Great Bivy for Moderate Temperatures

I bought this for lightweight camping out of my truck for trailheads and to co-use for my unit when we’re in the field. Overall, great bivy, waterproof, wind resistant and minimalist. I slept in this with my -10 degree (f) bag and was plenty warm. My con on this bivy, is the vent is not vertically above your ahead but horizontally. So, when sleeping the condensations sits above you and does not vent the same as its Alpine Bivy counterpart. I would use this for more moderate temperatures where I use less bulky equipment than my Arctic winter gear since I put my sleeping pad inside the Bivy with me. More than likely pair it with my lightweight jungle bag and a R-Value 5 pad which is less bulky. Overall, awesome and consistent part of my kit.

NOT WATERPROOF

Used once, failed miserably, got totally soaked. Had an old Goretex OR Bivy that lasted 15+ year. This thing is garbage. Called OR, and they refused a return b/c product was used. Zero customer service and a horrible product.

Great quick/light option

I’ve used this bivouac on a handful of excursions so far. It’s very versatile, sets up quickly, light weight, and the arch space over the face is a great comfort touch.

Mosquito Netting Poorly Designed

Familiarity:
I returned this product before using it
Size Bought:

This is my first time disappointed with a product from OR. To crawl into the Bivy you have to climb over the mosquito netting. There is no mechanism to tie the netting back or protect it from your body as you crawl into the Bivy. I expected the netting to attach towards the top of the bivy so that your body did not brush on top of it crawling into it. I expect the netting to rip very quickly.

Beware: NOT waterproof!

Familiarity:
I've used it once or twice and have initial impressions

We went on a trip to climb in the High Sierra in September. Bivy was brand new for my boyfriend. Rain started our first evening at 12k feet. Within a few hours, water had penetrated the fabric and was soaking his sleeping bag and all clothing inside. We bailed the next morning when we got a short break in the weather to pack up. This could have been a life or death experience, as temps were down in the teens. I have the OR Interstellar bivy (yellow bivy in photo) and I stayed dry during the entire ordeal. We noticed the fabric is much thicker on mine. Spend the extra money on a 4-season for rain protection.
