My Big agnes pads are very comfortable, but I have never had luck with them staying inflated. Reading about bicycle365's 300 nights on one makes me seethe with jealousy. Returned one, they tested it and sent me another, it went flat faster than the first. They sent me another, that stays inflated about six hours before my but hits the ground. A friend bought me one, and it goes down about the same. All of them are the Aircore.

One thing I can say, they are pretty durable. I have been using the first one they sent me that goes flat quickly to lay on working on a car. It does not stay inflated very long, but scooting it around on the dirt and gravel has not made it much worse.

Just my experience with the aircore, I love it, but keep having to back to my super old Thermarest.
