Giro Tenaya Spherical Womens Helmet 2025

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

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.
