You wouldn't buy a windshield for ten dollars. So, why would you buy sunglasses just as cheap Like your windshield, Julbo's Stony Sunglasses protect you from all sorts of eye damage, sun glare, flying rocks, dust, and the occasional friendly bug. Although this pair doesn't come standard with automatic wipers, it does come with Spectrum 3 polycarbonate lenses designed to offer the best in distortion free clarity when out on the trail for hours. A large, curved structure not only protects your eyes from damage at every angle but also offers you the widest field of view. Made entirely of grilamid, the Stony's frame, though lightweight, can withstand quite the beating. Rather than snap like most ten dollar frames, grilamid simple bends to disperse the pressure, then rebounds back into shape. Soft, yet grippy nose and temple pads, made with Grip Tech, will hold securely to your head without yanking your hair out when you least expect it.
