The light yellow lenses are tinted just enough to wear out in the daytime and cut the rays, but light enough to wear in the dark of night and still have full vision. Small rubber pieces in the ear and nose keep them solid in place when locked into your helmet and flying down the highway. Skinny arms make for an easy and comfortable fit in the helmet. The lenses are polarized as well, making sure you're seeing everything on the road, not the glare. The size and shape of the frame is perfect for blocking the wind when you're jamming your face into the wind, and they're lightweight enough to carry with you in a pocket when you don't need to be wearing them.
