Product Description Item No.   10237624

The Outdoor Research Helium Bivy is a minimalist shelter for solo adventurers. Because if it gets any bigger they'd just call it a tent. This ultralight shelter is made from Pertex® Shield+ 2.5L fabric, a 100% nylon with a floor that is tougher than the upper, for longevity and protection. The single pole creates enough space so your face isn't stuck up against the fabric and you can start catching z's with the no-see-um mesh exposed on warmer nights, watching the stars. In wetter weather, zip the whole thing up for waterproof protection throughout the night. Nobody wants their head getting rained on while they sleep.

Rated 4 out of 5 by from Good price/weight ratio I used this on my PCT hike in 2017, I got it for the high Sierras where I consistently had 10 degree nights or minus 15 degree Celsius, it added around 5 degrees to my sleep system, it will build up condensation but worth the the cut in comfort for the protection

Rated 5 out of 5 by from Fast, easy, light, cheap, anywhere all-weather protection Through my own personal experience and after years of buying different hiking shelters, this type of shelter is the go to every time for me (AT section hiker, < 4 days at a time, Whites in NH and Colorado). I currently have the OR net bivy as well and have been very happy except for its limits, which this bivy solves (rain!). 1) Add ultralight stakes like the Vargo titanium and you only add 40 grams (1.41 ounces) for all 5 stakes to the weight which will keep it tight and steady in higher winds. 2) Small footprint, it will fit in places that tents will not. It is a stealth camping enabler. 3) It will keep you dry with proper ventilation. Use a very small tarp or piece of it or a UL rain poncho (no need for pack cover either!) at the head covering the mesh and use 2 hiking poles on one side and 2 clips to tie it to the top of the arch/pole. You now have a vestibule and can set the bivy while everything inside stays dry. 4) You may be able to fit it in the same space allocated for a sleeping bag at a shelter. Adds warmth and puts an additional barrier between mice/spiders and you, just be creative in tying the head loop to a nail or any edge at the head to keep the arch up. 5) Easy 1 minute setup at the end of a tiring day. No messing around. 6) Cost is low compared to a $500+ tent of the same weight. If you pack ultralight, why do you need the extra space and the cost involved? Unless you are claustrophobic this should not be an issue. 7) I am 5'11 and the rest of the pack (sans food and scented items) as well as the shoes can be positioned strategically at the foot of the bivy for storage and to create additional vertical space which may reduce contact area between your sleeping bag and the bivy. 8) Star gazing. Besides the cons listed, closing it fully may trap some carbon dioxide, which, depending on your breathing may cause you to feel like suffocating or it may also be due to newly experienced claustrophobia.

Rated 4 out of 5 by from Pleasantly Surprised This was my first experience using a bivy and I wasn't sure what to expect. Everyone I talked to told me I would have condensation problems but this was not the case. My first test was a quick overnight on Mt. Adams. Our group found a windbreak at Lunch Counter and set up camp under bluebird skies. Shortly after dark, we started to get some rain so I climbed into the bivy and hunkered down. I stayed totally dry despite the on / off rain & mist we were getting. I'll admit it was a bit claustrophobic inside, but the light weight and ease of setup more than made up for that. After a full night in rain & mist, my sleeping bag and clothes were totally dry with the exception of a few drops of condensation at the foot. Really great first impressions here. Looking forward to taking the Helium Bivy with me on my Timberline Trail hike this weekend.

Rated 3 out of 5 by from What you'd expect My first time using a bivy sack, and the experience was exactly as I expected it to be. Don't bring along a bivy if campsite comfort is most important to you. However, the Helium takes up very little pack space and adds minimal weight, so it adds to your comfort while hiking the trail. I felt claustrophobic inside of it and needed to keep the exterior layer unzipped for airflow, which also made me a little colder at night. The four nights I've used it were dry with temps in the low 40's. Very little condensation collected inside and only near my head from breath. I'll continue to use this bivy when I am on solo treks or possibly river trips for the perks of low weight and packability. I didn't expect any bivy to be comfortable, as its built for function. Curious to see how well it works in rain.

Rated 5 out of 5 by from Light and packs super small Venting is fine if you leave the face part unzipped, otherwise it does get damp in there for sure

Rated 5 out of 5 by from Ultralight protection I bought as an ultralight shelter for romote areas in Montana high country while hunting, great product works well as an ultralight option. This will not work for you if need something more durable though.

Rated 4 out of 5 by from Stealthy! Have not the chance to use it yet, but tested it out for a night in my living room. Fully-zipped, it felt kind of suffocating as I find myself taking longer breathes. Other than that, it’s a nice stealthy bivy!

Rated 5 out of 5 by from Great bivy, use it for active duty infantry. Used in 30 degree weather with just this and a woobie and I kept warm all night. Protected me from the chilly winds

Should I use a tarp or pad under the bivy bag???

Asked by: Gaia
Hiya Gaia, thanks for your question! You will need the usual components of a sleep system... sleeping bag/quilt and sleeping pad inside the bivy. A tarp under the bivy is not necessary but you will probably want a tarp above it. Hope this helps!

How does this bivy cut wind?

Asked by: Sophia12
Hey Sophia, thanks for the question! The bivy's fabric is waterproof and windproof (but breathable), so wind will not get inside the bivy but hot air can escape. It has five stake loops and one guy line loop to help hold it down in the wind. I hope this helps!

Really like this bivey but how do you get the arch pole to stand up once you pull it through the fabic inserts, Not sure if Im doing something wrong but mine keeps falling over/down against the bbivey. Please advise.

Asked by: Tawa70
Hello Tawa70, thanks for your question! After you feed the pole through the fabric, there will be two velcro tabs on each side to insert the ends into. There should be the word &quot;pole&quot; and an arrow pointing to the tab. Once the ends are inserted, the pole should stand up on its own. If not, feel free to reach out to Outdoor Research directly to troubleshoot the issue. You can reach Outdoor Research at 855.967.8197. Good luck!
