These goggles will perform so well, you will request an Encore. This medium size goggle is built with an ergonomically designed, thermo-polyurethane frame that stays flexible, even in the chilliest weather conditions. The triple-density face foam keeps you comfy throughout the day and the anti-fog cylindrical lens gives you 100% UV protection and a wide field of peripheral vision so you can spot the Jerrys from a mile away.
