My first Thermarest pad was 18 years ago and it sleeps as well as it did on day 1. Since then I have acquired two more, one 2 years ago and the last one this summer of 03. I bought the extra thick one and boy is it great. My kids use them every year and I sleep better on them than I do on my new mattress which I purchased this January. Your office got the pad over to me overnight which was just in time because my trip started the next day. I really enjoy these pads and was very pleased to see that they come with a patch kit although I have never needed one. The Thermarest pads have never let me down and kept me dry many a night. Thanks.
