"Breathes just fine." 02/18/11
My first bivvy bag and I'm pleased. It breathes fine. I never felt like I was suffocating. No ridiculous condensation issues. It's light and packs small. Has little reflective bits on it which is nice for finding your bed at night. I can't figure out how to keep the part over my face UP when I don't need it down (like if it's dry and not cold), but the fact that it wants to lay closed hasn't been a major problem. Has nice little pocket inside for flashlight, etc. Also has tie downs for your sleeping mat. Fast setup. No complaints.
"Outstanding 1-Person Alternative!" 12/20/10
The Outdoor Research Alpine Bivvy is outstanding. It has performed well in sub-zero winter, spring rain, summer heat and dewy fall morning conditions. The single pole system assembles easily and helps avoid claustrophobia. My only criticism is that using the bug netting option is a little funky. It is important to maintain a 6-inch or greater opening to avoid condensation. I recommend practicing setting up and entering prior to your 1st trip in order to master. Carrying an additional small tarp for changing or gear protection defeats the purpose and weight advantage this product offers. Utilize your pack’s rain cover instead.

"If you have a 25 inch sleeping pad, skip this bivy" 10/20/10
Dry enough and not too claustrophopic, but it doesn't accomodate a large thermarest very well. One major improvement would be to have some way of keeping the outer shell pulled back when you only want to close the bug screen. A well-placed velcro patch might do the trick, but I haven't tried it since it won't fit my sleeping pad.
"Who needs a tent" 05/11/10
Doing high altitude solo excursions requires to count every ounce and this bivy can replace a tent if you dont insist on too much comfort and space. The Delrin pole keeps the face clear and allows to seek full shelter in harsh conditions. The GoreTex is great and will keep you dry as long as it's cold (and high and hence dry) enough to create a large gradient of water vapor pressure. I use it with a down sleeping bag, which naturally is very sensitve to water, and was always fine in the mountains. I guess any bivy is not good for warmer and more moist conditions.
"Perfect for going solo light and fast" 05/04/09
I do a lot of solo trips and it really helps not having to haul the weight of a tent alone. The screen netting is great for keeping the bugs out and letting the air in on nice summer nights. The storm flap is great for when a freak ice storm catches you and you need to hunker down for 36 hours (true story).The pole does a good job of keeping the material away from your face when either the screen or storm flap are closed. The picture shows the sleeping bag crammed right up against the edge of the bivy but in reality there's enough room to toss a book and a few water bottles above your head, essential for when you're stuck in there for 36 hours.
"Dont read this...Read this==" 07/12/08
Just the idea of a bivy is a wonderful thing, a beautiful thing, a historic accomplishment, but perfecting this dream was a long, rocky, and often ended bitterly in a cold, wet, miserable night in the middle of nowhere. Those hours of woe no longer need to be endured if you own this bivy. It fills the highest quality, waterproof, comfortable, and good looking marks of the U.S. Bivy Lovers Magazine. But unfortunetly, the U.S. Bivy Lovers Magazine does not exist, and my shirt is orange. I need to change my socks. That is all, thank you for your time and attention.

Paraphrasing Freedom of the Hills, bivy sacks are a bit of an acquired taste. If you don't want to haul an entire tent with you on a weight-sensitive trip, these are surprisingly comfortable and spacious assuming a pole to keep the fabric off your face. What's more, the Gore-Tex fabric is completely waterproof, which can't be said for some tent floors. Another use of bivy sacks is improving the temperature rating of a sleeping bag this was warm enough for me to sleep in without a sleeping bag in autumn during a cycling trip from LA to San Francisco n.b., I wore fleece pants, cycling pants, a cycling jersey, a lightly insulated jacket, and no socks.

"Well done - who needs a tent?" 06/11/06
I've been wanting to get a bivy for a couple of years now - I've used lightweight, high quality tents, but a bivy has some real advantages. A bivy sets up quickly, packs down to a fraction of the size of even a one man tent, and can be placed in a tiny location. <BR><BR>The OR bivy is well built (actually built in the US!), and surprisingly comfortable outside. I've used it while camping in lower Michigan under cool but very humid conditions. The bivy has little condensation inside, while all my gear outside the bivy has been quite wet. The Alpine Bivy sets up quickly, and the head pole give you a very large amount of interior room - it's like having a tent, and it helps prevents cluast
