The KASK Protone Helmet is incredibly aerodynamic and has a top performing shell, tested in the wind-tunnel and able to provide a really impressive CX rate. Any position the head will assume the outflow of the air will be perfectly in line with the helmet. It is classed as being part of the next generation of aerodynamic helmets, with the KASK Protone helmet leading the way in aero advantages and features that don’t compromise comfort. The specially designed Octo Fit includes a Rubberised Micro Dial adjuster to improve finger grip and the floating cradle contact points combine internal gel pads for optimum comfort. These support mechanisms are designed to oscillate freely through 180 degrees allowing a perfect fit on any shaped head. The Skeletal Brackets of the cradle have been designed and refined to provide the best fit and support whilst being as light as possible.
