I've taken one of these on numerous camp outs and treks, its nice and light, but sometimes I wish I had a real tent. It weighs next to nothing, which is great, and its waterproof to the point where you can float away in it, but it doesn't breathe, at all. If you zip that thing all the way up or leave too little a gap, you will suffocate, I made that mistake once and woke in a panic and almost tore it apart. This can be avoided by leaving a bigger opening, but as I experienced just last night (in a downpour), its just enough for the rain to get in, and I had an inch of water everywhere. Also with it closed up, it ends up being wetter inside because of the condensation. Its wonderful on clear nights, when you can have it open, or just the screen, but in the rain its miserable without a tarp to go with it. Also, the pole in the center doesn't do anything, in fact, quite aggravating. When its just the mesh, you can't keep it wrapped around the pole like in the video, and when its closed, its just saggy enough to lay on your face. Overall, light, but extremely uncomfortable in anything but clear weather.
