Costa Tasman Sea Sunglasses, This body of water between New Zealand and Australia has been called one of the roughest stretches of sea in the world. The gripper temple holes of these large frames will keep them in place on any journey, and they’re just as useful while you kick back and relax behind their beach styling. Bio-based resin is used to stay mindful of both the sea and the shore.
