Awesome (Review by Calvin)

Took this gem on a Grand Teton and Rainier climb and it performed flawlessly. I'm 6' and it has plenty of room for me. I had no issues with condensation. My only concern is the bug mesh. It is zipped in a strange way and occasionally gets caught in the main zipper.

Doesn't live up to claims (Review by Ray)

I tested this bivy hiking two weeks on the west highland way in Scotland. It held out the rain but I frequently had a LOT of condensation on the inside of my bivy and it never actually hit freezing. Enough condensation was present to the point that my sleeping bag was quite wet at the tip and on the sides. A less important issue, but something to note, is that the insect mesh layer is really easy to get caught in the outer zipper and I made a small hole in mine within a week that I had to glue. This was partially my fault, but still something to note for people purchasing: use caution when zipping.

Outstanding bivy bag! (Review by Harry)

I purchased this in August of 2014 and have used it several times, both in winter, as well as wamer applications. I have yet to experience any condensation and this is my lightweight alternative now to bringing a tent. I am somewhat claustrophobic, but have done fine in this, with the headroom that the pole offers.

Excellent product (Review by Harry)

Kept me dry in wet humid conditions. I've used this bivy twice now in Olympic National Park--one on a dry climb and the other a wet. It kept me dry on both occasions with no condensation, even though the dew was heavy outside of the bag. My only complaint might be that it is a little hard to get into, since there is no lengthwise zipper, but without one the advantage is there is no way for this bag to leak. The mosquito net that touches your face when in use did not bother me. It is made of bombproof fabric and I can tell it will last for years. There is no place here to add a photo or I would add one of this product at my stay at Constance Lake.

Awesome well constructed (Review by the Grizz)

this bivy is awesome. worth every penny. there was alot of thought that went into this product it is reinforced and sturdy where need be and feels beefy all the while lightweight. there is piping around the entrance which is genius.

Alpine Bivy (Review by Murcus)

I’ve used it on two winter outings now. First was a January trip into Glacier park. Built a snow trench and was sweating all night. Second trip was last night. Headed into the Montana Rockies for an overnighter. When I reached camp, I started digging a snow cave and after three feet of digging I found ICE. I was too exhausted to do anything else so I just made a shelf and put the bivy up. It anchors in quite well with the loops. Throughout the night the wind blew ONE FOOT of snow on top of me, I recall waking up on occasion to shake what I thought were a few inches off. Nope, when I unzipped in the morning my boots, gear everything outside was under a foot of snow. This bivy kept me 100% dry and protected from the elements. Protip, boot a hand warmer in your boots and let the wind bury them in snow, they’ll be warm in the morning. Zipper is somewhat tedious, though I wouldn't knock the bivy because of that. Fits me, 5’9” a thermarest zlite pad, and a 0’ sleeping bag perfectly with room to spare.

Alpine bivy (Review by beldarski)

Recently purchased a couple of Alpine bivy's for doing glacier hikes, summits and such. Left Timberline lodge at 6:30pm and snowshoed up to Illumination rock to dig in for the night. The bivy sack is super light and nice and small to pack which made the trip up way more enjoyable. It unrolled and I had the poles inserted in just a couple minutes. The pad straps inside were awesome and held my airpad under me all night long without sliding around. The temperature was around 0 degrees so any condensation would freeze instantly and in the morning it looked like it snowed inside the bivy. My only complaints are the inability to zip it all the way up and even with the pole and bivy tied down the material continually drooped onto my face during the night. (going to buy a few poles and create my own modification to correct for the drooping material) This bivy kept me cozy and dry all night!!! Great value~

Alpine Bivy (Review by By MB)

This bivvy fits nicely in a modest sized camelback, weighs next to nothing, and couldn't be easier to use. I'm about 6' and 200 lbs, yet this bivvy was roomy and comfortable. The only drawback I have found is the rain fly - the only easy way to keep the insect mesh closed and the rain fly open is to lay on your back. It needs a little magnet or bit of velcro to hold it open so you can read comfortably on your stomach.

Alpine Bivy (Review by By Mac the Angler)

I use this product for overnight / multinight tramping, hunting and back country fly fishing trips in New Zealand. Alpine Bivy Bag suits temperatures up to 20 C, no moisture inside bag, unlike cheaper bags.Also extremely weather proof.Mat strap great inside bag. Packs up nice and small. My only advise is BEFORE going the Bivy Bag option check if you can actually sleep with a bag right above your face, several friends have sold their Bivy Bags as they are claustraphopic.

Alpine Bivy (Review by By Robert)

Great allround bivy. I usally use it on hiking trips with a tarp. Waterproof. I`ve never had any problems with condensation. The only downside for this bivy is to keep the mesh opening open all night.

Alpine Bivy (Review by By enduro)

I'm 185cm and the bug netting presses against my forehead a little which means I can have some bug bites through the netting.This is the second Bivy I have owned, and the width and construction of the Alpine is excellent. After 3 years of regular use in the wilderness, this bag shows no sign of giving up. Packing down to a 1L weight it's marvelously small.Two design additions I'd like to see: * have a clip so the hood can stay up all night. I've added my own. * ventilation at the toe end to eliminate condensation.

Alpine Bivy (Review by By thefellow)

I have owned this bivy for 2 years and have put it to the test. It stood up to snow and pounding rain in the high country on many occasions without incident. I use it more than any other shelter I own. I can't say enough about this bivy.

Alpine Bivy (Review by By Willapakid)

This bivy is great.. I picked it up a year ago and it has gone everywhere with me from camping on top of Mt. Rainier to the Columbia River Bar (Both in WA, USA) it has been an excellent addition to my gear collection. Bivy survived +50 mph winds one night on whiskey dick ridge above Ellensburg WA. I'm impressed and keep it up OR.

Alpine Bivy (Review by By Isaac)

This is a great bag that I carry on all my missions, and personal trips. It is light weight, and fits in a 1L bag when rolled up. It is totally waterproof, and when the rain cover is rolled up, the single poll still keeps the bug netting your face, which is a godsend for the slightly claustrophobic. By adding loops for it to be staked out OR has made sure that as you move in the night the bag stays right side up, and does not shift on the ground.

Alpine Bivy (Review by By crow)

This is the shelter you want to take on fast and light mountaineering trips, traverses or multi day backpack adventures into the high country. This shelter has contributed to the success of several summit attempts in the Cascades and the Olympics. The Alpine Bivy, combined with a basic tarp is unrivalled for lightweight protection from nasty alpine elements and refuge from bugs. It is probably one of the fastest shelter systems to deploy in adverse conditions.

Alpine Bivy (Review by By Cal)

Love the bivy. Excellent quality, very comfortable. It is easy to set and gives good head space. The mesh comes in the face, that could be improved, and maybe a hip hight zipper. This bivy is dependable gear.

Alpine Bivy (Review by By David T Connolly)

I have been using my OR Alpine bivy for a couple of years now and I have to say it is the finest bivy on the market. I have used it in all kinds of conditions and it has never let me down. Speaking of down I have a down sleeping bag so condensation is a major issue with me. The only time I have had any condensation was below freezing and it collected around the foot area only. It works great when camping in below freezing weather in a tent as well. I sleep in it with the top wide open so that when I exhale and my breath freezes and falls back on the bag it lands on the bivy keeping my bag dry.
