I've considered the Thermarest, but it is a little heavier than I would like for the kit. I would prefer it to be 8oz. or less in weight. The Big Agnes is nice because it only weighs 6oz. I'll have to see if I can order one and try it out. Although, they look like they won't be out until July 16th.
