Nike Therma Sphere 3.0 Neckwarmer Black/Silver

Dri-FIT
This high-performance, microfiber, polyester fabric drives sweat away from the body and moves it to the fabric surface, where it evaporates. As a result, Dri-FIT fabric helps you stay dry and comfortable.

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.
