I have tried many pads. From the cheap blue closed cell foam, the egg crate z-rest to the self inflating. I am a self prescribed weight watching weiner when it comes to packing my gear. The self inflating pads produced such a great nights sleep it made the cut anyway. The best sleep you will ever have is to ditch the pad altogether and get a hammock. Much less bulk than a tent and the bulk and weight of a sleeping pad is no longer necessary. A double savings and a better sleep.
