The Obex SPIN offers adjustable protection for various ski and snowboard styles. The Obex is made of an EPS liner, a PC scale and an ABS scale and is lightweight, making it ideal for everyday use. A system for adjusting the inside size allows a user to find an ideal fit without changing paths. With sliding ventilation hoods, the wearer can open or close the ventilation of the helmet based on his own comfort and the prevailing weather conditions. Integrated ventilation openings on the front of the helmet ensure that air can escape from the glasses, preventing condensation.
