Sometimes thicker is better.
I have a 3/4 length lightweight backpacking Thermarest, but wanted something of same quality for my wife. This pad out did my pad. It was twice as thick, which equals more comfort. It was a bit bigger and might be harder to strap to the pack, but very doable. If you are thinking of getting rid of your eggshell mattress and actually sleeping on your camping trip--upgrade to this! Do it!
