I bought this sleeping pad to replace a Thermarest Prolite from 2010. Overall this new product line from Sea to Summit is a C+. A comfortable model but a little too pool floating mattress for me.
Tested it at home against Thermarest's new Evolite and preferred it; A-. It had the same loft, as good support but a much better comfort level. I'm sure Sea to Summit will get lots more feedback and version two will be better.
