Featuring our custom low and snug fit, the Evolution helmet sticks to your head like no other shell. Anatomically shaped it smoothly curves around your head for great fit and wearing comfort. We took a complete new approach when developing the Evolution as the helmet is not only molded on front and back as common half-shell helmets but is also greatly shaped on the sides. The Evolution is the choice for almost our entire skate, bike and bmx team and shape role model for all our halfshelf helmets. Versatile helmet.
