Horsefeathers Proton Photochromic Sports Sunglasses

Horsefeathers Proton sports glasses are designed for everyone who wants maximum performance without compromise - whether you're going cycling, running, hiking or just spending an active day outdoors. They combine modern design, low weight and cutting-edge technologies that ensure perfect vision in all conditions. The main advantage is high-quality photochromic lenses that automatically adjust to the intensity of sunlight. They darken in bright sunlight, and brighten in poorer light conditions.
