The DGX Rio two lens mask is a popular design with larger lenses and offers a slightly larger faceplate and lens area, with the tradeoff that the mask is not quite as low volume. The mask skirt is made of high quality black silicone for superior comfort, fit and durability. The mask also includes a black high-impact plastic frame and tempered glass lenses, with an easily adjustable strap. The DGX Rio double lens mask fits most medium to large faces, but may not a good choice if you have prominent facial hair. Also available with gauge reader and vision-correcting lenses. Includes the DGX padded mask bag.
