Sunglasses designed for climbing. All the climbing sunglasses selected have large lens sizes for unrestricted vision and many have a removable strap to keep them securely in place. Interchangeable lenses provide clarity of vision in different light conditions and can also be replaced if scratched without replacing the whole frame. The Cebe Crux also has a flexi nose bridge, which allows the frame to properly cling to your face providing a great secure fit.
