Costa and music superstar Kenny Chesney have partnered again to offer five limited-edition sunglasses, available in late May. A portion of the proceeds benefits the Coastal Conservation Association. Last year’s Chesney Costas raised more than $50,000 for CCA. The five new styles include Hammerhead, Caballito (pictured), Switchfoot, Hammock and Maya. Each features the singer’s signature and palm-tree logo inside the frame; the collection comes in a variety of unique color combinations, including tortoise/light green, black/white and clear/light blue. Cost is $129 to $199. Call 800-447-3700 or visit www.costadelmar.com.
