OR Highland Bivy
I would recommend this bivy to anyone, and esp. for the price. As has been mentioned, condensation seems to be an annoyance...but such is the case with any waterproof membrane that sits only inches from the body. On windy nights, I'd recommend rigging something to keep the body of the bivy from flapping around alot. While free-standing, it has kept me up more than one night when the bag repeatedly slapped me in the face with gusts of wind. Asides from these minor items, this bivy is pretty awesome and takes up little space in the pack, which is of course the point! OR has a solid product in the Highland Bivy!
