Sea to summit self inflating pads

[westsloper]

I’m a big fan of self inflating pads and have always gone with thermarest. I am in the market for another pad though and was looking at the self inflating options from sea to summit. They seem to be a little thicker for the weight than thermarests, but also made with lighter materials (less durable?) The valve has one-way deflation, which is pretty sweet.

Has anyone used these pads enough to get a sense for their quality?
