The Giro Stellar MIPS is one out of this world helmet for ladies looking for that perfect fit. Giro's Conform Fit System and Articulating Hard Shell Construction has a two-piece shell that can form to the different shapes of skier's heads with a turn of the dial for a perfect fit. The Stellar is equipped with MIPS (Multi-Directional Impact Protection System) that has a low-friction liner that can rotate upon impact. The rotation of the liner absorbs energy rather than transfer it onto your brain. Thermostat Control allows you to adjust the amount of airflow into the helmet with a switch on the top of the helmet that keeps air moving through the helmet to cool you off when you start to get warm, or close the vents when you start to get cold. The Stellar MIPS has a Fidlock Magnetic Chinstrap that uses magnets on each end to make closing the chinstrap a cinch, even with mittens on. Stack Ventilation keeps air moving through the top of your goggles to prevent fogging. Just in case you want to use a helmet cam to record your ski adventures, and Integrated Camera Mount will give your viewers the perfect POV.
