BETTER EYE PROTECTION AND VISION – Our swimming goggles feature wide polycarbonate lenses with advanced anti-fog coating and UV-proof plating (Cat3 UV400 Standard) for a clear 180-degree field of view and undistorted optics above water and underwater. MORE COMFORT – These swim goggles offer soft and flexible silicone double seals designed to expand and contract to fit the unique contours of a swimmer's face, providing a secure seal without excessive pressure around the eyes. The ergonomic 3D frame design ensures low water resistance and a comfortable fit for a wide range of face shapes for men, women, adults, and teenagers. SUPERIOR DESIGN – Unlike single strap swimming goggles, our split Y-shaped strap design helps keep the goggles securely in place on the head, even during intense swimming. The one-click buckle system allows for easy, fast strap adjustments, even while in the water. LONGER LASTING – These swim goggles are made entirely of high-quality silicone, and the lenses are constructed from polycarbonate, providing excellent impact resistance.
