MIPSA(R) EVOLVE CORE - All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro&';s MipsA(R) Evolve Core-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet&';s adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider&';s brain in certain impacts.
