A glasses keeper for water enthusiasts and athletes the Costa Megaprene™ Retainer slides onto frame arms with a firm, tight, grip. The wide design keeps them comfortable when glasses are on, or when they’re hanging around your neck. Keep your favorite shades secure with a retainer designed to take on the rigors of sport and one that’s easy to rinse free of salt spray, sand, and sweat at the end of the day. At over an inch wide this is not your wimpy dime store glasses keeper, but one designed for serious sport fishermen who don’t have a hand free to mess with keeping glasses in place when the big one is on the line. Can’t you see it? In the middle of landing the big one, it is this close to the boat.. and you have to make a grab for your glasses? Are you going to risk your tackle, or your favorite shades? Let’s not have to make such decisions by making good decisions up front. Get yourself a Megaprene with the width and grip to secure your specs even under the stress of ocean fishing and surf casting. Anyone who goes for the best in gear knows, it’s the little details that make a difference. An extra ¾ inch on a strap doesn’t sound like much, but it’s double the width of a conventional glass keeper, and yes, it makes a difference. When you have a choice? Get the best.
