The whole package
This mat has it all, and it should for its category leading price. The size, weight, comfort, and included repair kit are the main selling points and aren't equalled by any other mat I've seen. My backpacking buddy uses a Thermarest that's larger, warmer, and thicker, and I always look at it with a little envy when setting up camp, but when packing my bag or wearing my backpack, I'm always thankful I bought this. I've used it in sub-zero conditions, on multi-night backpacking trips, car trips, and even for guests at my house and my hips and shoulders never touch the ground while using it (even sleeping on my side). Proper inflation level is key, so figure out what's best. No rips or leaks, easy and quick to fill and deflate, and doesn't make as much noise as a Thermarest.
