The X-Bionic Helmet Cap is more than just an accessory. With its special 3D Bionic Sphere system, it cools when you sweat and warms when it’s cold. The Sweat Traps system quickly wicks moisture away from your head, and the cap fits perfectly to its shape. It also features a special insulating layer that does not interfere with hearing. The cap is recommended for use not only in winter – it is perfect for running, cycling, hiking, and skiing (it can be worn under a helmet on cold days).
