The ARENA The One swimming goggles , here offered in Navy and blue with transparent lenses, are ideal for your training. These swim goggles are waterproof and provide crystal clear visibility. In addition, they adapt perfectly to all faces. The gaskets of The One goggles are structured to avoid areas that compromise the suction effect on a face. Enjoy the best possible vision underwater, with oversized polycarbonate lenses, shaped for forward and peripheral visibility and treated with an anti-fog coating for a crystal-clear view.
