Made in a comfortable Universal Fit size with Giro's convenient Roc Loc Sport fit system, the Register MIPS adjusts with a simple turn of the dial so you can tune the fit in seconds. A range of colors lets you choose exactly how your on-bike style comes together. Register MIPS models also have an integrated Multi-Directional Impact Protection System, which can redirect energy and provide more protection in certain impacts.
