The OMS Double Lens Clear Frameless Mask features a low volume teardrop design and a soft black silicone skirt. With a very large viewing area this mask offers excellent "down" vision as well as a wide view of the environment surrounding you. Lenses are approximately (3 in | 7.6 cm) horizontally. The low volume and nose pocket make it easy to clear as well as pinch the nose for equalization. Tempered glass as would be expected for safety. OMS logo in center between lenses and on bottom right lens as well. Fits standard to wide faces.
