Watersports whilst wearing glasses? This practical glasses retainer is a sporting essential. The flexible rubber ends of the fabric strap are suited to various sized glasses frames. The anti-slip material has a firm hold on your glasses whilst underwater, even on smooth plastic frames! The 27,6 inch-long sports strap can be individually adjusted to fit your head size and desired tightness thanks to a plastic stopper. What's more, the glasses retainer floats! The sports strap remains buoyant with glasses weighing up to 1,6 oz. What more can a floating sports strap do to help if you lose your glasses in the water? For this reason our glasses retainers are available in noticeable and trendy neon colours - easily to spot in water and against dark backgrounds. The glasses pictured are not included with delivery.
