Giro Ratio MIPS

The Ratio Mips is a function-oriented helmet without frills, inspired by the features of Giro's premium helmets. Beneath its sleek silhouette, it features an In-Form adjustment system, adjustable thermostat ventilation openings, and compatibility with aftermarket audio systems from Outdoor Tech. The Multidirectional Impact Protection System offers increased safety during falls by reducing the rotational forces that can be transmitted to the brain.
