ROKA KONA PERFORMANCE SUNGLASSESThe Birthplace of Ironman Inspired by the Hawaiian birthplace of IRONMAN, an annual proving ground for the latest in performance technology, the Kona has a modern, square lens that echoes iconic American style of the 50s and 60s. At just 24 grams, the Kona is remarkably lightweight and incredibly durable while still delivering razor sharp optics.GEKOPatented Fit and Retention SystemDESIGN EVOLVED OVER A BILLION YEARS. Inspired by the soft but amazingly sticky feet of the gecko, our patented GEKO™ fit and retention system features a proprietary elastomer for nose and temple pads that’s hydrophilic, chemical resistant, and supports multi-directional traction with comfort. It’s also designed to not snag hair.No matter how sweaty you get, and which way you move, bounce, or shake — you’ll never have to worry about slippery frames falling off your face.ROKA C3 Lenses +Advanced CoatingsROKA optics are more that just a lens. We design for performance in the real world. The advanced coatings we use are applied in an ultra clean manufacturing process that ensures quality and consistency. Each coating is applied, cured, and tested for purpose built performance and transmission. Each lens is coated, custom built for the “as worn” position and cut to specific geometry. These aren’t blanks bought and cut in bulk to fit whatever style the market wants.We don’t cut corners on coatings that are mission critical to performance and quality to save dollars.
