Therma-FIT
Nike Therma fabric represents the best defense against extremely rigid weather conditions: double-brushed microfiber fleece that retains energy and resists heat loss without added weight. In addition, the breathable structure prevents the product from retaining sweat allowing it to be expelled: this helps keep the skin dry and guarantee maximum comfort.
