This pad is super comfortable and packs very small. I had been using a self-inflating thermarest, but I sleep on my side, and I always woke up several times during the night because my hips were killing. Not so with this pad! I slept very well. I have a Big Agnes sleeping bag, so it slid into the sleeve, so I didn't fall off the pad.
The only reason I'm giving this 4 stars instead of 5 is because you have to blow it up, which takes several minutes and some dizziness if you don't take breaks. I've heard that too much moisture can get inside it from your breath, so I put my bandana over the blow-hole (not sure if that helped, though).
Overall, a great sleeping pad and definitely recommended, especially for side-sleepers.
