I have used this on 4 different 3 to 5 day backpacking trips, plus I have had numerous drunken friends pass out on this pad. ALPS Mountaineering has done it again, great quality product at a price you can afford. This air pad is soooo easy to use, just unroll, let it inflate itself, and then blow air into it until it is at your desired firmness. I have noticed that throughout the night I have had to put more air into it, but I believe that it is a very very common issue with ALL of these type air pads after you have used them as much as I have. I have these types of air pads fold in half, and then roll up where this pad simple rolls up and is a bit longer in your pack, however it holds more air than the ones that folds in half, and you don't have an annoying creese in the middle right where your but is. To sum it up, it is bigger than normal, but if your out for numerous nights it is worth it to be comfortable.
