Giro Register Bike Helmet with MIPS

Synthetic
IN-MOLD CONSTRUCTION - In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets
INTEGRATED MIPS - All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated MIPS-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to the rider's brain in certain impacts
UNIVERSAL FIT SIZING -Our Universal Fit helmets are sculpted to look good and fit great for almost anyone on the first try. By developing proprietary shell sizes based on specific customer groups, and combining them with an easily-adjustable fit system, it's easy for you to get the right fit, straight out of the box, without the hassle or expense of trying multiple sizes

Its confident clicking feel and sound lets riders know that the helmet is adjusting to a comfortable fit. With comfort similar Roc Loc 5 and ponytail compatibility, the new Roc Loc Sport fit system brings premium function to sport level helmets
