    Superlight, super reliable in rain and snow.

    Outdoor Research equipped the two-pound Alpine Bivy with waterproof breathable Gore-Tex Respiration Positive to keep you comfortably dry while backpacking in wet weather. Gore-Tex's Respiration Positive provides more breathability than standard Gore-Tex membranes, giving you more comfort throughout the night. Outdoor Research's Hydroseal Floor and fully taped seams further prevent snow and rain from seeping through.

    When it stops snowing and raining, the Alpine Bivy unzips to reveal a no-see-um mesh window for ventilated airflow and bug protection. There are straps inside to secure your sleeping pad, and an internal mesh pocket stows your alarm clock, smartphone, or GPS watch. Outdoor Research included five stake loops, a loop for a guy line, and a Delrin pole that you can either use for more headspace or leave at home to save weight.

    Great for climbing in a Canadian summer

    • Familiarity: I've used it several times

    This is the perfect balance between the functionality of a tent and the packability of a bivy bag. I first used it for a week of alpine and crack climbing in Squamish and it was dry through the thunderstorms and cozy camping on snow above the treeline. Leave it about 3 inches unzipped for fresh air and expect condensation in cold climates but (if your roughly my size 5'8" 120lbs) expect it to have all the room you'll ever need for you, and all your gear.

    Good but not perfect

    • Familiarity: I've used it several times

    It works fine - a bit claustrophobic with a pad and 20 degree down bag - except you need to use clothes pins to keep the flap open fully and use the big screen, and when it's closed you feel like you will suffocate in minutes. They need to add some Velcro to keep the flap up and improve ventilation possibilities when flap is down.

    Best piece of gear I own

    • Familiarity: I've put it through the wringer

    This bivy is so dependable and bombproof. I've been caught in some nasty rain and this bivy has never leaked on me. No problems with condensation, as far as I'm concerned this is the best bivy on the market.

    High Quality, Well Built, But Alas, it Collects Moisture

      This was my first bivy and it had nearly everything I wanted. It's small, light weight, east to pack. It opens to fit into a space a couple feet wide and 8 feet long. There's ample space for my sleeping bag a book and a water bottle. There's also good headroom for a bivy. I found it to be warmer in cold weather than my tent. The Gortex really blocks the wind. It cool weather, there's not much of a condensation problem.

      I had the problem that many other reviewers had. The pole is cheap plastic. I was surprised that it wasn't something a little stiffer. It would have been great if there was a way to run lines from the the arch to tie points on the ground. This may have kept the top from flopping closed. When the top was closed in moderate (40F+) weather, moisture collected on the inside and my down sleeping bag was damp from condensation in the morning.

      This was my first bivy. Even though it's lighter than a tent, It's not that much lighter than some ultralight tents. If I'm going to give up the comfort, storage, and options a tent offers, I opt to get a lighter weight bivy for the summer.

      Perhaps I can't get away from my tent. I like to have my backpack in the vestibule to keep it dry, and close by, along with my boots. I like to move around a bit and a bivy is restrictive. I also camp in groups so sharing a tent often weighs less per person than using a bivy solo.

      I recommend the bivy for cooler weather camping when you don't share a tent. It's light weight and keeps you warmer than an ultralight tent.

      Positive for me

        The bivy have some littles lacks but at this price i think is a really good piece of kit. I used it at my place one night, just for try (420m on the sea lvl 1° celsius, no condensation), was like be in a "warm bubble"; very nice... For now i did nothing serius whit it but probably will be my shelter in future all around. Very light to carry, easy and fast to set up, must try it when snowing; i need to know the limits...

        works for me

          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.

          OR Alpine Bivy on Tettegouche River in Minnesota

          Here is my bivy set up on a large rock outcropping in the middle of a river. (haha, i know not a smart location but I'd rather risk drowning in a flash flood then spend a lonely night in the thick woods worrying that there is a cougar hiding behind every tree around me). Oh, and my footprint is 2x the size needed because I forgot my real footprint at home and hand to use my tarp to protect the bottom of my bivy from all the sharp rocks.

          OR Alpine Bivy on Tettegouche River in Minnesota

          Bivy++

            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.

            As good as bivying gets.

              Pros: Really light, completely water proof, packs small, bug screen is a nice touch.

              Cons: Pole does not stay up so the bivy collapses on your face, stake loops are too small (fine for low altitude & soft ground, but not great for alpine bivys or deadmanning), not breathable at low altitude & when it's warm outside.

              I took this for some extended trips through the Adirondacks and it was great. The pole does nothing to keep it open though, so you don't really get the stargazing experience one would expect with the bug screen. I've spent some storms in it and was as comfortable as one can be in a bivy, but the goretex doesn't really breath when it's warm so you get some serious condensation buildup.

              All in all a great light weight solution for soloing in the mountains - I'm taking it out for a season on colorado's 14ers.

              Well & truely tested, 3 mths nz winter/ spring conditions

                We have just completed a 3 month stint around NZ on the push bikes, combined with a Sea To Summit Overhang tarp shelter our bivvys have been working a treat.

                They did arrive with some minor delamination bubbles, particularly around the entry which we intend to deliberate on with Outdoor Research, apart from this they were of exceptional quality.

                They definitely hold the rain, snow and frost out in the most appalling conditions and providing the pegging loops are used top and bottom to open the bag up to allow condensation to escape they stay dry inside also :)

                I have found a trick for keeping the hood right back so you can just use the fly, you work all the fabric back up and over the pole till the hood is inside out (can b a litttle tight but do it bits at a time like putting a tyre back on a rim)
                then just pull enough back over to zip up fly. Attach a carabiner to the loop and run a occy strap down to a peg on the ground.
                For full weather protection without dying of suffocation, place your boots covered by a waterproof bag directly in front of your bivvy, zip your fly all the way up and pull the under section slightly back so the outside can drip straight to the ground and then drop the top section down and over your boots slightly, no probs!

                Be careful not to damage the pole sleeve by shoving too hard, it may pop through the far end, as my partners did!

                Turn them inside out regularly and air, avoid leaving damp in bag, we aired ours out regularly and they still have a little mold.

                Great for fast-packing.

                  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.

                  My only qualm is the same as the other guy said; it's difficult to hold open both the netting and/or the waterproof flap that goes over the head when you want open air... I had to modify mine with some velcro so it would stay put as I moved around at night.

                  Close to perfect

                    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.
                    If the next version could have an easier way to fasten the netting and to keep an air-space open, it would be perfect!

                    Does this have a full length zipper?

                    Does this have a full length zipper?

                    does anyone have experience with the length?...

                    does anyone have experience with the length? I'm 6'1 and was curious if there would be enough room to maybe put boots to keep warm and dry?

                    Some sites have a blurb about this bivy, stating that it was designed for use with thicker mats such as the downmat 7. I have a downmat 7 DLX and the stated demensions of this bivy (specifically the width) makes it look like it might not fit. Anyone know if it does/doesn't?

                    How exactly does one set up the pole? I'm having some trouble in that I can't find where it needs to hook in on the side opposite the "Pole ->" logo. Thanks!

                    Has anyone used this in the snow? Any details on how it does? Thanks!
