Six years ago, Giro set a new standard in quality, look, and feel in a recreational helmet with the original Register. The Register II takes this to the next level by bringing styling and venting of Giros highest-end road helmets into this lightweight in-moId helmet. With a removable visor, an adjustable fit system, and the Mips Evolve Core rotational energy management system, the Register II Mips is a best-in-class recreation helmet. - MIPS EVOLVE CORE All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giros Mips Evolve Core-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmets adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider in certain impacts. - RUGGED: In-MoId Construction fuses a tough polycarbonate outer shell with the helmets impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-moId helmets lighter and cooler than traditional helmets. - ROC LOC SPORT FIT SYSTEM The Roc Loc Sport fit system offers easy one-handed operation with a 7cm adjustment range. Its confident clicking feel and sound lets riders know that the helmet is adjusting to a comfortable fit. With comfort similar to Roc Loc 5 and ponytail compatibility, the new Roc Loc Sport fit system brings premium function to sport level helmets. - DEEP INTERNAL CHANNELING Combined with the massive 19 vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power. - Quick Link removable visor - Reflective rear decals - Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older E.U.: CE EN1085
