“Is there such a thing as too much blue?” With ‘Rainwalker,’ we answer with an emphatic, “No. No, there is not.” A polarized sky blue lens stretches wide, nearly from ear to ear—if you could somehow wear a perfect, cloudless day, this would be it. The frame and temples get a complementary azure aesthetic thanks to satin metallic blue paint, and everything is finished in a rubberized coating for an unrivaled full-coverage fit and feel.
