Serving up the lowest profile fit of Giro's expansive helmet fleet, the Giro Women's Stellar MIPS Helmet precisely wraps your head with its two-piece articulating shell. Conform Fit technology goes beyond other helmet's adjustable liners with its semi-flexible hardshell, controlled via an adjustable dial. This innovative design results in a streamlined fit without the bulky, bobble-head feel of traditional helmets. The Stellar MIPS seamlessly integrates with Giro Goggles, courtesy of its subtle brim that eliminates unsightly gaps.Going beyond the helmet's superb fit, MIPS technology helps absorb impact from damaging rotational forces from angled crashes. Customizing airflow with the quick flick of a button, Thermostat Control provides on-the-fly ventilation adjustments during warm spring days and socked-in storms alike. The Stack Vent sits over the top of your goggles, preventing condensation build-up during nasty blizzards and sweaty uphill slogs.
