Equipped with the highest levels of protection, the Giro Tenaya Spherical Helmet is your one and only. This versatile dome protector utilizes the MIPS® Spherical Technology™ to ensure you stay safe when you get tossed off your feet. Not only do you have the adjustable venting feature for all-day comfort no matter the conditions, but you also have the Stack Vent that keeps your goggles fog-free for superior visibility through it all. The plush interior padding also provides comfort and warmth for peak winter days where you’re putting in work from first chair till last. You’ve only got one noggin, so treat it real nice in the Giro Tenaya Spherical Helmet.

Product Highlights

MIPS® spherical

A new technology developed jointly by Giro and MIPS in Sweden, MIPS® Spherical uses inner and outer EPP foam components to allow a “ball and socket” rotational movement of several millimeters in any direction during an impact.

Thermostat Control™ 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.

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.

IN FORM 2 FIT SYSTEM

The In Form 2 Fit System is lighter and lower-profile than the original, and easier to dial in a custom fit in seconds – even with gloves on. An improved dial design provides up to 6cm of adjustment plus enhanced stability.
