Costa Tasman Sea SunglassesClarity is key and looking through the polarized Tasman Sea sunglasses from Costa provides a crisp and sharp view of what lies ahead. The frames are made of eco-conscious, bio-based resin instead of petroleum-based plastics and are sized to fit larger faces. Hydrolite rubber grip tabs on the nose bridge and at the end of the temple arms help keep the glasses in place even—especially—in wet or sweaty conditions. And for those more involved pursuits, there are holes at the end of the temple arms to tie on a retaining strap and/or a float. The Tasman Sea style is available with lightweight polycarbonate plastic lenses in five different lens colors and four frame colors or with durable glass lenses in two different colors and two frame colors. They can even be made to order with prescription lenses. $249 (glass); $169-$189 (plastic) | costadelmar.com
