Kaenon's flagship performance sunglasses, and the most universal of the Kore series.

Kaenon might not feel like a brand name that's on the tip of everyone's tongue, but for those who prefer sunglasses with supreme construction and the highest-quality materials, Kaenon is a well-known entity in the world of optics. Kaenon offers a range of performance sunglasses for running, boating, and biking, but when it comes to choosing just one, the Hard Kore Sunglasses are the flagship model that many reach for again and again. Lenses, fit, and frame design separate these sunglasses from the rest of the pack, and each is designed for a fast-moving lifestyle. SR-91 plastic gives the lenses razor-ship image quality, durability superior to that of polycarbonate, and a weight that's lighter than glass. The semi-rimless frame is made of TR-90, a material with a slight flex but rock-solid durability. And the fit is close and secure thanks to thick, contoured temple arms with a streamlined sweep, and nose and temple pads that resist sweat and moisture to keep these shades in place. Run trail, paddle on your longboard, or hammer out some singletrack on your bike, it's all the same to the eyes behind the Hard Kore.

Kaenon's Hard Kore sunglasses are part of the Performance collection. More technical than Kaenon's Lifestyle collection sunglasses, the Performance collection shades offer the most attention to detail, closest fit, and performance-oriented designs. Within this collection, the Hard Kore sunglasses offer the most universal fit and style of the Kore series, which also includes the larger Kore and smaller Soft Kore shades.
