Seven Protection presents the Project23, a downhill and enduro full-face helmet made from carbon. It is tested to CE, CPSC, AS and ASTM F1952-15 standards and is characterized by generous ventilation and a high level of safety - not least thanks to the "S.E.R.T Slip Plane" system. This reduces and distributes the impact forces and thus reduces the risk of concussion. In size L, it weighs just 922 grams.
