Riding at breakneck speed is hard enough without having to contend with blinding sunshine, fogged up lenses, or oncoming elements obscuring your vision and creating dangerous hazards. Satisfying your need for speed, the Ryders Eyewear Crankum Sunglasses deliver crystal clear optics, 100% UV protection, and impact resistant lenses for riders pushing the limits of what's possible. Immediately noticeable, the semi rimmed, broken frame design optimizes ventilation for fog free clarity and an extremely light feel. The grilamid TR 90 frame is flexible and extremely tough, withstanding the rigors of daily rides and active use. Fully adjustable nose and temple pads dial in a truly custom fit, making slipping and re adjustments a thing of the past. Also, these pads are hydrophilic, meaning they'll absorb sweat build up while retaining a sticky fit. Retaining clear vision is the difference between avoiding obstacles and suffering a nasty slam on the road. Realizing this, the Crankum Sunglasses feature a scratch and impact resistant polycarbonate lens for high levels of eye protection and precise optics. Hydrophobic and oleophobic lens coatings disperse oncoming moisture while repelling dirt, oil, and grease build up from clouding your vision. This lens also filters out high energy blue visible light 400nm wavelength for enhanced protection from macular degeneration.
