Description
Made to provide visual clarity in ever-changing light conditions, the Rapha Letras Photochromic Sunglasses can take you easily from low-light overcast conditions to bright sunshine. Featuring proprietary lens technology to improve contrast and Rapha's Freeform lens shape, the Letras offer a far superior fit than a traditional curved lens. The result is better coverage, with UV rays less likely to get behind the lens, and a wider, uninterrupted field of view for optimal clarity tuned specifically for cycling performance. The lens also features a hydrophobic coating to prevent water and mud sticking and the anti-fog and anti-scratch finish maintains a clear view for the long haul.
Weighing a mere 28 grams thanks to the frameless design, the Letras sunglasses are barely noticeable when on while MEGOL™ arm grippers provide a reassuringly secure fit even in the wet. A choice of interchangeable nose pieces lets you tailor the fit and the strategically placed ventilation prevents overheating and fogging.
