Overview
A closed-cell foam sleeping pad from Therm-a-Rest that folds accordion-style to 20 x 5 x 5.5 inches and weighs 14 ounces. A reflective coating and molded dimples give it an R-value of 2.6 for ground insulation on backpacking and hiking trips.
This is the pad backpackers reach for when they want zero chance of a mid-trip failure. There is no valve, no bladder and nothing to patch, just dense foam with a softer top layer for comfort and a firmer bottom layer against the ground. The tradeoff for that reliability is a firmer, less plush sleep than an inflatable pad delivers.
- Accordion-fold closed-cell foam, no inflation needed
- R-value 2.6 with reflective ThermaCapture coating
- 72 x 20 inches unfolded, 14 ounces packed weight
- Made in the USA
Who it's for
Suits thru-hikers, backpackers and anyone who wants a sleeping pad that cannot puncture or lose air overnight. Less suited to car campers or side sleepers who prioritize cushioning over weight and reliability.
Pros and cons
- No inflation, valves or air chambers to fail
- Doubles as a sit pad or gear cushion around camp
- Packs down to 20 x 5 x 5.5 inches at 14 ounces
- Foam construction tolerates rough or rocky ground
- Firmer underfoot than an inflatable pad
- R-value of 2.6 is modest for cold weather or winter
- Folded shape is bulkier on the outside of a pack
Performance notes
The R-value of 2.6 comes from a reflective ThermaCapture coating combined with heat-trapping dimples molded into the foam, which the brand states raises warmth retention by roughly 20 percent over a plain foam pad. The two-density foam construction puts a softer layer against your body and a denser layer against the ground for durability.
