evo.com | Giro Ski and Snowboard Helmets > The Giro Tenaya Spherical Helmet is where modern freeride styling meets serious tech, with Spherical Technology powered by MIPS reducing rotational forces through clever two-part construction that actually works when you need it most. A Plush Max lining keeps things cozy while In Form 2 fit system and adjustable venting let you stay comfortable whether you're hiking ridgelines or cruising groomers with the kids. In Form(TM) 2 Fit System The In Form 2 Fit System is lighter and lower profile than the original, making it even easier to dial in a custom fit in seconds - even with gloves on. An improved dial design provides up to 6 cm of adjustment plus enhanced stability. Stack Ventilation Stack Ventilation was developed based on research showing the majority of the warm air that can cause fogging exhausts from the center top vent of the goggle. Aligning the Stack Vent in the helmet with the center vent of your goggles helps to keep them clear and fog free while maintaining total helmet and goggle integration. Thermostat Control(TM) Adjustable Venting Allows you to custom tune airflow instantly with a simple, low profile control button on the outside of the helmet. No other system is faster or easier to adjust, and nothing is more effective at keeping you comfortable. Fidlock(R) Magnetic Buckle Closure The pinch-free, one-handed Fidlock Magnectic Snap helmet buckle combines the advantages of two fastening concepts in a completely new way. Strong magnets make it easy to open and close while a secure snap functionality ensures a continuously high locking force.
