The 100% S3 Sunglasses fuses the features of the two most popular models, the Speedcraft and S2. They are made with high-impact resistance and lightweight 5. 5 -base cylindrical shield lens for increased peripheral view and protection while you ride. The 360 degree visibility for unobstructed views and optimal field of vision so that you're ready for anything on the road or the trails. The Grilamid TR90 frame is lightweight and shatterproof so you can be confident in knowing these glasses will go the distance. The finishing touch is the ultra-grip rubber nose pads and tips which give you a secure fit no matter how much you sweat.
