I was impressed with this bivy. Seems to stand up well and provides good protection. It is a good compromise between weight and protection. Enough room to put your boots inside to keep them dry. Rolls up pretty small and sets up easily. To try it out I took a February night in upstate NY that it was going to snow. Set it up in my back yard with my Dark Star sleeping bag. Temperature was down around 5 deg F. I just set it down on the snow with my pad and sleeping bag inside, no ground cloth outside. I heard it snowing and even sleeting during the night. In the morning I noticed that the floor felt like it had slight condensation. The top part was dry to the touch. I was dry and so was my sleeping bag. I did notice after I pulled out my Thermarest that it had condensation on the side that I slept on from sweating. I think this is where the condensation came on the inside floor of the bivy. Came with seam sealer which I have not used yet. Did not come with any directions but the pole to set it up was easy to figure out. So far I am impressed.
