Sprint into style, fit and comfort with Ryders shades. They sport extra-durable Duraflex frames that bend rather than break under pressure, so you can take them down the toughest trails. The optically correct photochromic lenses adapt to changing light intensity so they're perfect for long days in varying light and weather conditions. They're also shatterproof, scratch-resistant, provide 100% UV protection and are vented for increased airflow and reduced fogging. Plus, they stay on your head, even during strenuous activity, thanks to hydrophilic temples and nose pieces that get tacky when you sweat.
