While Costa started as an eyewear brand built by saltwater anglers for saltwater fishing, their advanced polarized lens technology and attention to detail appealed to a wide population of adventurers who demand performance and style in their sunglasses. The best Costa sunglasses are some of the ‘old favorites'—styles that have been around almost as long as the brand itself—like the Rincon, Tuna Alley, and Spearo. In these sunglasses, Costa combines lightweight design, sporting style, and LightWAVE™ polarized lenses in a variety of tints to enhance your vision on the water, mountain, golf course, or wherever adventure takes you. A keen focus on performance puts most of Costa’s sunglasses on impressively even footing, so narrowing down the best Costa styles wasn’t easy. We looked at fit, coverage, and fashion (current style elements and timeless design) when all else was equal. In the process, we scrutinized the brand’s entire catalog of frames to bring you this collection of what we think are truly the best Costa sunglasses this year.
