The Finnish-made Kaira Litetrek pad is incredibly lightweight, especially suitable for summer use as a protective layer under an airpad. Since the pad is even thinner than a "gas station pad", it is only suitable as an actual sleeping pad in optimal conditions, e.g. if you're camping on a sandy beach. A pad made of foam material is worry-free: even if a branch or a dog's claws perforate the material, its insulating ability will remain largely intact. - Dimensions 190 x 50 x 0.3 cm - Made in Finland The R value for this pad has not been tested, as it's made primarily for use as a protective layer under an airpad.
