Knockaround never said that your sunglasses have to be overachievers, but the Knockaround Mile Highs sunglasses pretty much set the standard. These shades are well-equipped for anything—they’re polarized aviators, after all—and are made with durable, long-lasting components that’ll keep them (and you) flying high in the long run. Each pair of Knockaround Mile Highs features slim, metal frames in the same teardrop-shaped silhouette made famous by World War II pilots. And to keep you glare-free at any altitude, all Mile Highs come with polarized lenses.
