The Giro Ceva MIPS is a fantastic value and loaded with style. Giro's In Form Fit System uses a dial located on the back of the helmet to help you get the fit adjusted to a safe and comfortable fit. Stack Ventilation helps prevents your goggles from fogging up by keeping air moving through the foam on the top of the goggle. MIPS (Multi-Directional Impact Protection System) uses a low-friction liner that can rotate in the event of an oblique impact to absorb the energy rather than transfer it onto your brain. Giro's Thermostat Control has adjustable vents that allow you to regulate the amount of airflow through the helmet to prevent overheating and keep you comfortable on the slopes.
