warm as toast
i'm 5'5 120 lb female, i used this bivy in 22 degree temps with my marmot zero degree lithium down bag, a thermarest prolite 4 pad, a northface 800 fill down jacket and a warm hat. slept toasty warm, but mild condensation at foot of bag made me a bit concerned as to what would happen in colder temps. a small zipper at the foot of the bag might take care of this problem, but maybe OR is concerned about waterproofness. might add a footprint as recommended by other reviewers to step on when getting in and out of the bag. overall very happy and will probably replace my msr hubba tent to cut down on weight.
Excellent bivy for cold trips
After searching long and hard I choose the OR alpine bivy for its ruggedness and its extra head room. This is a fully sealed gore tex bivy with a little head extra room. When comparing to most bivys this is pretty light weight at 30oz by my scale and has an extremely fast setup time. Just one plastic tent pole. I have used this on many trips in Moab deserts to the Rocky Mountains and just be aware being gortex it does not breath very well, so if its warm you will be sweating if you dont keep the flap open. It is also difficult to get in and out of since it has no side zipper but thats the compromise for a water proof yet light weight bivy. I would say its one the best bivys I have tried yet.
So much better than a tent
This thing is amazing. If you've slept in a traditional one-person backpacking tent, this is going to be very similar so long as you consider one fine point: Others have mentioned the poor hood design - YOU NEED TO USE TENT STAKES. Seriously, doing so will allow you to keep everything taut so that lip/edge of the hood can be rolled over the pole such that it will stay put (this should make sense...) If you're really concerned beyond that, you can use a clip to hold it in place. But, I can't stress enough the importance of tent stakes. Yes, something that should probably come with the bivy sac, but an easy fix - fyi - get the MSR's.
Bought for climbing used for backpacking.
Bought for alpine climbing. Ended up using for last minute, 19 day backpacking trip (don't have an ultralight 1p tent). We had 9 days of rain/hail. Others had expensive tents from big name companies and got very wet. One companion in the end said "maybe a bivy is the way to go." Have a TNF bivy that was pretty terrible. The pole and ability to pull the vortex back and have just netting is great. Was never clammy when not raining. Did not tear in marble sized hail. Just wish the pole was neon and not black as I know I will lose it eventually. Can fit myself, shoes, spare clothes etc all inside.
amazing but can get wet
this has to be the best bivy iv ever used. most of my hiking is down in the winter and living in New England there's a lot of steeps and heavy tree coverage so for me a tent just doesn't work. every time i have used this i stayed super comfortable and dry. iv been out in a hurricane with tons of rain and it held up like a champ. my only downfall is i recently got a dog and when sleeping out in 0 deg weather so of course the little one decided to cuddle in with me so after the two of us in there the amount of condensation was outrageous how wet my sleeping bag got oh and don't sit up to fast if it really cold out cause sometimes you'll get icicles
Just what I need
I'd rather sleep under the stars than in a 5 star. For years I've traveled with a pad and a 10'x10' nylon tarp. I finally broke down and got this to replace the tarp. Just finished a 3 day trip and it works fantastic. I did not get to test in in wet conditions. It was dry and cold where I camped and there was zero condensation in the sack each morning. I did not need the netting or cover over my face as the bugs all go to bed before I do. I love to look at the stars/moon between short sleep periods all night long. Based on how it worked I can imagine it is exactly what I've been looking for. Very pleased.
Perfect!
Humphrey's AZ in the winter- very warm and cozy. Yosemite in early spring with rain- warm, dry and cozy. I don't mind close quarters and this bivy is just about perfect. One pole, packs relatively small, Gore-tex dry, though I did get a small amount of condensation that froze on the wall. There is enough room to move around a little and I spent some time inside and read a book in the rain. I think it is fantastic!
Awesome
Tested it at 4300m (14000 feet), -2 to -6 degrees celsius (22F), with a 0°F sleeping bag. I stayed warm all night and had just little condensation. Very comfortable.
Smallest Packed Shelter I Own
I bought this a couple months back for use as a small solo shelter for myself. I didn't want to take up much space on the ground and I didn't want to have to worry about guylines sticking out. Basically I want to hike or run all day and then lay down wherever I end up and go to sleep. This isn't the lightest shelter option ever, but it packs down a whole lot smaller than my cuben fiber tarptent. It's just slightly larger than a 48oz nalgene bottle. When I'm trying to keep my load small and close to my body that really helps.
Good, except the hood
The OR Alpine Bivy is nice for a solo backpacker. It does not take much time at all to set-up or take down and the weight is low. I have spent some cold nights in it in the snow and it does make a big difference keeping you warm. My biggest problem with it is the terrible way to secure the hood open to allow more cold air flow in when the night ends up being warmer enough to open it all the way, but you don't want to open up the bug mesh. I end up wrestling with it all night as there is no way to secure the hood open. I have tried staking it and pulling the lip over the hoop, but it always flips over when I turn or the wind blows just a bit. OR would it have killed you to add a clip or Velcro to secure this?? I guess I will just have to add it myself.
