The One goggles have special seals using arena's Orbit-Proof Technology. The seals are designed to avoid areas around the eye socket that interfere with suction. That way they’re watertight on any face. The wide hard lenses offer panoramic and lateral vision. The split headband is easy to adjust at the side and provides a stable and comfortable fit, even with long hair. The lenses have an anti-fog coating, UV protection 400, and are PVC-free. A protective bag for the glasses is included.
