Costa teamed up with Mark Healy to create his signature frame, the Sampan. This all-day style and performance capabilities make the Sampan a perfect frame for any adventure you seek. Named after the traditional Chinese fishing vessels that still work in Hawaii, the Sampan features a hydrophilic material along with the temples, a vented hydrophilic nose pad, TR-90 Bio Resin Nylon frame material, and a 6 base lens design. Pair the Sampan with Costa’s 580 technology to experience unmatched clarity and definition.
