Overview

Accordion-fold foam at R-2.0 and 14.5 oz. It is bulky, it is not plush, and it is the pad that still works on night nine when everything else has developed a slow leak.

RidgeNote verdict

At 14.5 oz with an R-value around 2.0, this closed-cell folding foam pad uses a ThermaCapture reflective coating to retain body heat. Backpacker consensus highlights its durability: it never punctures, absorbs water, or deflates. However, reviewers acknowledge that the thin foam is not plush on hard ground, and its folding bulk forces external pack attachment. The plain tradeoff is pack volume for complete immunity to pops. It suits a warm-season hiker or a winter backpacker adding a booster under an inflatable.
