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, 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.
  • 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.
  • FIDLOCK® MAGNETIC BUCKLE CLOSURE — The pinch-free one-handed Fidlock® magnetic 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 continuous locking force.
  • THERMOSTAT CONTROL — 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 VENT TECHNOLOGY — Our Stack Vent was developed based on research showing the majority of warm air that can cause fogging comes from the goggle's center top vent. Aligning the Stack Vent in the helmet with the center vent of the goggle helps keep it clear and fog-free.
  • HYBRID CONSTRUCTION — Hybrid Construction merges a durable ventilated Hard Shell upper with an In-Mold Construction lower shell plus sidewalls for added protection and style. With Hybrid Construction the helmet is beefed up for added durability while remaining lightweight. Hybrid Construction also features an impact-absorbing and lightweight EPS foam liner.

Bike Helmet Size Guide

How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
