Amber Rose goggle lens that Giro uses on select youth goggles is a perfect all conditions lens. The amber base tint and rose coating work together to help heighten detail and contrast when light is low or flat, as well as provide 100% UV protection for sunny days. This lens has a 40% VLT rating, meaning it allows only 40% of light from the visible spectrum to pass through. A good, all around goggle lens you can count on from opening day to your last spring ride.
