The Arena Air-Speed Mirror swimming goggles feature polycarbonate mirrored lenses providing extra protection against UV rays while swimming outdoors cutting down on glare from the sun and in well-lit pools. Those goggles are equipped with innovative honeycomb air seals that are designed to compress and adapt to your face, distributing the pressure only where needed, for a super-light feeling. In addition, the interchangeable nose bridge and dual adjustable strap provide long-lasting comfort and a custom fit to help maintain the glasses in place.
