It has high heat retention and quickly absorbs and diffuses sweat to keep the skin dry. The box structure, which connects a smooth surface layer and a soft skin-contact layer with partitions, retains dead air (air that does not move as an insulation layer) to ensure heat retention. The smooth surface makes it easy to put on and take off layers. Suitable for activities that involve repeated action and rest, such as mountain climbing and tour skiing. It is useful in the cold seasons from autumn to spring.
