Exceptionally lightweight, the Julbo Tracks Sunglasses (3 Lens Set) manages an array of light during bike, run, active, or casual pursuits. With small frame and temples, this aero style fits comfortably on all face sizes (the Tracks Light is made for smaller faces). Its polarized 3 lens, which provides 100% UV protection and blocks 91% of intense light, is scratch/impact-resistant and eliminates sun dazzle or glare on any reflective surface. Switch out The Hi Contrast lens that blocks 88% light for flat light conditions, or the Clear that blocks 10% for windscreen protection.
