Our Blade Cycling sunglasses offer maximum coverage and an ergonomic design for greater comfort while riding. This innovative design offers riders the opportunity to switch between half-frame and full frame glasses depending which frame coverage and appearance is preferred. The Polycarbonate lenses offer high definition, more natural coloration, and unmatched clarity. TR90 frames provide adjustable nose pads for a firm fit regardless of face shape, and the adjustable cushioned nose pads ensure the glasses stay put on rougher terrain.
