Tenaya Spherical Helmet Details


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, our In Form 2 fit system, and adjustable venting. And for the highest levels of protection, we arm the Tenaya with our proprietary Spherical Technology™, powered by Mips®, to reduce rotational energy during certain impacts through our unique two-part construction.

Tenaya Spherical Helmet Specs


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 an 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.


Developed at the Bell+Giro Dome laboratory in partnership with Mips®, Spherical Technology’s unique Ball-and-Socket Design redirects impact forces, bringing market-leading design, performance and brain protection together without compromising comfort, ventilation, weight or style.
