These look and feel like good-quality sunglasses, with really well-made frames that are light and seem tough. The ImpactX lenses are made from NXT, a material which Rudy Project say was developed for the US military to be strong, shatterproof, light and clear.
The photochromic lenses mean you don’t have to swap; they respond quickly to changes in light and our testers found they gave very sharp vision, and stayed clear. However, though they were comfy enough, the frames were small for cycling and didn’t have the same forget-about-them feeling of others we tried.
