Building from the success of the Re-Akt 150 we see the new Vapor Hyperlite helmet share some similarities to that model with how easy it is to adjust. That is all they share along with a great shell design to pass that mirror test. The Hyperlite helmet has a new lining inside that is designed to provide a lightweight feel while giving elite level impact protection, Bauer calls this new lining the SHOCKLITE, the SHOCKLITE foam paired with the molded liner with added XRD Foam will give you the comfort you would expect from this helmet.
