Inspired by the sophisticated black-sand Karekare beach, the Costa Kare Shiny Black Hibiscus sunglasses is a bold and fun look to every outfit. The Costa Kare small frames inherit their beauty from the area's unforgettable scenery, and offer thin lightweight construction, optical spring hinges and Hydrolite nose and temple pads for extra comfort and no-slip grip. Like many of our sunglasses, Costa is reducing their carbon footprint to help save the planet's waters by using bio-based resin for their frames.
