Hi : I sleep on
"Hi : I sleep on a Thermarest every night and sit on it four about 4 hours every day. The matt I just bought looks like one I got back in 1992. It lasted before blowing a bubble for 10 years with every day use. Since then the Trail lite had one last for 3 years but most of them blow a bubble within a year. I think you would like to talk to me about my experiences with Thermarest, RUTH"
