Performance takes on a new level of clarity thanks to the dual curvature of the toric lens. With a half-frame design, they provide maximum peripheral vision and the crisp visuals of contrast and color-boosting ChromaPop for a terrain-defining view. Whether you're blasting through the trees or rolling in the open, the two-position nose pad and adjustable, corewire temples keep them secure at any pace. Interchangeable lenses lets you pick the right tint for the day.
