Powerful paired magnets, a deep frame channel and a curved-down end piece give Tenaya lenses extra retention stability. The temples bend behind the ear to fit securely and comfortably, while distributing pressure across the entire length of the temple. The bridge is short to maximize airflow. And while Avalanche is all about compound curves and mass, and Headwall is about being lightweight, Tenaya's good looks stem from sleek lines and aerodynamic curves.
The Peak lens provides excellent sun coverage for action sports, and is narrow enough to be a good choice for Rx wearers.
Magnetic Interchange Lens System - Switch uses high-energy magnets embedded in the lens and frame to enable users to swap lenses quickly and easily as light conditions and activities change.
