Sleek styling, premium optics, and a lightweight fit make the Kaenon S Kore Polarized Sunglasses ideal for the demanding runner or cyclist. Kaenon's proprietary SR 91 lenses offer razor sharp clarity and premium impact resistance in an ultra lightweight lens, and they're polarized to eliminate glare so you can see the road or trail more clearly. The lightweight and flexible TR 90 frame won't weigh your face down on long rides, and it's durable to withstand abuse. Hypoallergenic Variflex nose pads keep your shades from slipping when you're working up a serious sweat, and a protective hard case secures them when the clouds move in.
