The Alpine Bivy™ has everything necessary for long nights above tree line.
Perfect solo adventure companion, the Outdoor Research® Bivy sack will let you sleep undisturbed. So whether it is the black flies in Maine, downpours in Ecuador or a fresh snowfall above the tree line, this OR Bivy bag will be your best friend
The Alpine Bivy Bag by Outdoor Research is almost like being in a tent, but without the hassle of setting up. The Alpine Bivy bag is designed with a Gore-Tex Respiration Positive+ fabric which offers complete protection from rain and snow storms without collecting interior condensation. Constructed with an overlapped zipper opening that allows air to flow, without letting water or wind in.
Outdoor Research made the two-pound Alpine Bivy with waterproof, highly breathable Gore-Tex Respiration+ fabric, which makes it an excellent lightweight shelter for camping, climbing, and mountaineering. When weight is of the utmost importance, bring the fully seam-taped Alpine Bivy instead of a tent. This one-person shelter from Outdoor Research has a single overhead pole to keep the fabric off your face as well as mosquito netting to keep those nasty sub-alpine mosquitoes off you while you sleep. The Alpine Bivy also includes internal straps to hold your sleeping pad in place, a small mesh pocket for organization, and five stake loops so you can secure this shelter in wind.
Protect yourself from wet weather and pesky insects in the Alpine Bivy from Outdoor Research. This sack employs a single overhead pole to give you overnight breathing room while the GORE-TEX fabric lets you rest up without feeling clammy even during a downpour.
Sleep through howling weather with the protection of Gore-Tex fabric. The anti-fungal Hydroseal 200 coated floor resists punctures and prevents puddles from soaking through. Fully taped seams provide storm level protection when you need it most and a single Delrin pole overhead gives room to breathe. An end opening zipper with a wide storm flap provides a secure seal against the weather.

Travelled through the French Pyrenees for 23 days with it, absolutely great, it held fast through thunderstorms and extreme winds. Takes 2 minutes to put up and to pack away. Also, because it doesn't matter how lousy you put it up, you can put it on any piece of stony cramped swampy more-or-less flat two-square-meter piece of land, which is fantastic when bivouacing. One drawback is the moisture, some wetness forms on the inside but it's very managable if you sleep with your head as close to the opening as possible. Second slight drawback is that rain forms puddles on your fabric if you don't lie with your legs stretched, though probably the gore-tex won't leak anyway. Two suggestions: first one is to use tape and some rope to make a system that keeps the closed netting standing up by tying it to the little loop on top of the pole. Otherwise the head cover keeps falling down. Second suggestion is to keep some air-space open by putting your shoes (if they are water-proof) with the toes out of the tent and with the tent cover over the opening of the shoes. Otherwise the air space is difficult to keep open and you get moisture inside. | |

Solid Sierras Choice | |
| Rating: | |
| Now, I've only officially used the Alpine Bivy once in the field. It was last weekend at Treasure Lakes in the Sierras. The approach was only 2 or 3 miles, but I definitely noticed the difference in weight between the bivy and my 2-person tent. The weather was pretty hot, being mid-July, but the interior was comfortable probably due to the light, breathable material. I had no problems getting an inflatable mat, a large sleeping bag, and myself inside, and the netting protected me from the irritating swarms of mosquitoes that were by the lakes. It could be due to a number of factors, but I had one of the best-slept evenings I've had in the mountains. The only two issues I had with the bag were the zippers and the pole/hood. I'm not a big zipper fan in general, but zipping the opaque cover and the netting was a bit of a pain. Getting the pole into its proper place was a larger hassle, and the hood flops a bit. Overall, I thought the bivy was great and seems to be one of the better ones out there. I haven't tested it in harsher conditions, but since I'm using it to climb all the California fourteeners, I will. | |

One important thing that I discovered after the first time I used it is that you really should use some tent stakes with it - they are needed to get the effect as shown in the picture. The stakes also help greatly with getting your sleeping pad/bag in there and help when you climb in. I noticed condensation inside but that is pretty much the norm for every bivy out there. I have used it in the rain and it performed very well. One advantage to the thick fabric is that it really helps to keep you warm. I used it one night on a fishing trip last week at Flaming Gorge where the temperature was in the low teens and noticed a marked difference in warmth over the previous night where I was not using the bivy. The only reason i give it 4 stars is because it takes a while to set up and the stuff sack is pretty tight so it takes a while to put away as well. | |

i got one of these about a year ago and ive taken it out a few times out in joshua tree. im 5'11" so there wasnt much room for my boots, but i had no trouble with the wind no matter which way i turned it as long as i zipped up the front, just leave about four inches for breathability. the pole was perfect for keeping it off my face and giving me enough room not to get tangled up like i do in my issued one. the bug net is great cuz i can leave the main flap open when its gettin warm, zip the bug net and not have to worry bout anything joining my for the nite. lookin forward to taking it out this winter. | |

I picked up one of these from an REI garage sale to complete my trail running overnight setup. It packs down extremely tiny and is truly waterproof (weathered a couple downpours). If you have a warm sleeping bag then this is the perfect shell. | |

Great overall product | |
| Rating: | |
| I just bought this bivy even after looking at the first customer review which was rather negative. I have to say, I had no problem with the pole going in or out. As long as you use your palm to push it out instead of pulling, it works great.My only complaint is it didn't come with stakes which you will want if you want the most head room. That is a small problem easily fixed since stakes are easy to get.Overall, I think it's a great product. | |

| This Bivy is great for all conditions. Works great in 100 degree heat of the desert and in the freezing temps. of Mt Whitney. I wont use anything else, accept if I tarp it under the stars, which the Alpine Bivy is great for on a dry night. For the weight you can't beat the water proofness, insulation, and quality | |

| Rating: |  |
| This would be a wonderful little bivvy. Except that they seriously skimped on the quality of the single pole. Its very time consuming to get it in, and often comes apart and starts trying to fold up while in the sheath(very nit-picky and troublesome to then take it out, put it back together, and have another long go at setting it up). Since i usually have to set up FAST, this defeats the whole purpose of the thing. Very Frustrating! When it did eventually get the thing up and running, it was dry and as comfy as you'd expect a bivvy to be. The screening helped stop condensation, and the dark blue was great for my stealthy too cheap to even pay the fee at a hostel needs. But I had to bring it back cause of that silly pole! EMS used to make a wonderful little bivy very much like this- only BETTER. And it was BLACK too, which is what the urban explorer types who want a thing like this need(not neon orange or chartreuse or sunny good morning mister police man yellow). I hope ya start making those again! Consider your underground weirdo market, please! | |
