The new Tenaya™ spherical helmet sets a new standard in premium all-mountain performance.

Modern freeride styling teams up with advanced technical features to provide fit, comfort, and protection for long days chasing the perfect turn, exploring the mountain with family, or venturing into the backcountry. Warmth and comfort are driven by the Plush Max lining, Giro's In Form 2 fit system, and adjustable venting. And for the highest levels of protection, the Tenaya has Giro'sproprietary Spherical Technology™, powered by MIPS®, to reduce rotational energy during certain impacts through our unique two-part construction.

What is Spherical Technology?

The unique ball-and-socket design of Spherical Technology utilizes two separate liners to help manage impact forces. The material and density of the inner and outer liners can be optimized with Progressive Layering to help manage a broad range of impact forces: the Insurgent features and outer EPS layer (to address high-speed impacts) and an inner EPP layer (with rebound characteristics designed to handle slower speed falls). When you combine the benefits of Progressive Layering with the market-leading MIPS Brain Protection System, which can help redirect rotational energy away from the brain, you get more comprehensive protection.
