Sunglass specialists RETROSUPERFUTURE have linked back up with American street-savvy workwear stalwarts Carhartt WIP for the fifth straight year with a collection of stylish, sporty and innovative frames, including two new silhouettes -- the Genesee and Seebaldt -- that take inspiration from classic street- and sportswear, respectively. The shades are all outfitted with Zeiss lenses for good measure. You can shop the entire collaboration here.
