Compared to ordinary mats, the foaming rate has been adjusted to be higher to reduce weight, and the material itself is moist and non-slip. Heat is reflected by vapor-depositing aluminum on the surface. In cold seasons, you can get warmth by reflecting body heat with the aluminum side facing up, and in hot seasons, use it the other way around.
