Light weight, packs down small!

Great Bivy! Super light weight and comfortable. Love that the bag that comes with it is generously large and easily fits the bivy plus my inflatable pillow (one little luxury :)

What a killer Bivy!

So I had used bivvies in the past in the military. This is not one of them, in a great way. Some friends and I took a trip recently to an area that is fairly notorious for high winds. Some other friends had told us their tale of woe of high winds thrashing tents at night in the area we were going. Well, I had wanted a bivy, so I used that as my excuse to get one. It's only a pound, and it packs down small. Let me say that again- IT'S A POUND. I put that in my pack, and used it every night. I'm not saying it replaces a tent in all conditions, but on this trip, there was a little bit on jealousy over my bivy. Sets up and packs away as easily as a sleeping bag, low profile, simple...

As a wildland firefighter, I spend a lot of my summer sleeping under the stars. I learned after my first season how much difference a bivy sack can make when you wake up covered in morning dew at 5am and you have to pack up to go back on the line. This bivy is small enough to pack away without taking up much room at all. Its water resistant enough that morning dew is no longer an issue (I have not slept in it in the rain yet). And it is tough enough to use on a 14 day roll up here in the pacific northwest. If you want to pack light, keep dry, and protect your sleeping bag from being scraped up, this is for you.

I purchased this bag and took it Climbing in the Rocky Mountains.initially I was afraid it was going to be not enough however it exceeded my expectations. Bivied at the base of Mt Jofre an 11,000 + feet peak. we BV just at the base of the glacier with winds of around 80-100 km/h however while inside of the bag I had no problems with condensation, and setting it up was very easy and fast. We also had some light rain during the night and it didn't affect me at all. And my sleeping bag is only a -7. I honestly think that I had even a better night that the rest of my group that was sleeping on a descent tent. Another pro was definitely the light weight, just over 500 g. Can't beat that!!!! My only concern , reason why only 4 stars, is that the the part of the bag that rests on top of the rocks is the same thin material as the whole bag and I'm concerned that some rocks could easily damage it . It would be nicer ,in my opinion, if the base was made of a slightly stronger material or if there was a footprint to protect it. Overall, a great bag, very light that I will not only carry for BV's but also as an emergency shelter in case needed.

excellent so far

i rated it at a "4" because I've only used a half dozen times but it has been flawless. Pro's: lots of room, breathed well in semi-humid conditions, packs up really small, waterproof, pole works great, cheap! Con's: I see the 2.5 layer not breathing as well as its 3 layer counterparts once the cold weather camping starts up but cannot say for sure, almost too roomy/ or baggy.

I bought today your helium bivy sack and I like it since it's very light weighted and seems easy to set up. but, I really don't know how to install pole inside the sack. this is the first time that I ever try a bivy sack. can you please give your instruction to set up this one ?? there is no manual nor instructions inside the package. your instruction in details would help me a lot. awaiting your prompt response. thank you from Kwon in New York City

There is a sleeve on the outside of the bivy that you thread the pole through once you have assembled it.
