Overview
Inspired by our Froyd optical frame, Kostin scales up the classic optical silhouette with a robust acetate frame and an optimized fit for use as a sunglass. The result is a rounded sun frame that’s timeless and versatile, with nuanced details like a keyhole bridge, split bar tack hardware, and flipped temple design. Kostin is available in our Recycled Black and our Bio acetate, for those that want style and sustainability.Frame Measurements
