Kona

Modern Performance, Squared

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. These sunglasses are made for active people, and patent-pending GEKO Pads on the nose and temples minimize slip retention and maximize comfort, even during the most strenuous and sweaty activity. Hidden-spring hinges offer shock absorption and optimal fit for any head size or shape. Engineered channeled air-flow combats fogging and is reinforced with carbon fiber for enhanced torsional rigidity and strength. Impact-resistant nylon lenses from Carl Zeiss Vision deliver outstanding optical clarity and offer anti-scratch, anti-fog, anti-reflectance, oleophobic & hydrophobic coatings. Lenses exceed ANSI Z87.1:2015 impact standard for drop ball, high velocity and high mass; and they filter out 100% of all UVA, UVB, UVC and harmful blue light up to 400nm.

Handcrafted in Italy.
