The Crankum is fully adjustable meaning the nose pads and temple tips can be tuned for a perfect fit. The semi-rim, broken frame design optimizes airflow and reduces weight.
Impact resistant and optically correct, these lenses provide 100% protection from UVA, UVB and UVC rays as well as harmful, high energy light to 400nm. As if that’s not enough, they also have premium hydrophobic and scratch-resistant coatings. This is the standard from which we build all of our more technical lenses, so every Ryders lens has the same technology at its core and the highest standard of quality.
