Overview The Genesis Sigma Mask is a lightweight, compact dive mask designed around a wide-view single lens for an expansive underwater field of vision. Its frameless, low-volume construction keeps the lens close to the face, creating a streamlined profile well suited for recreational scuba diving, snorkeling, and travel. A soft silicone skirt and strap provide a comfortable, flexible fit, while the easy-adjust strap and quick-connect swivel buckles simplify fitting and removal. The reduced internal volume also makes the mask easier to clear and helps simplify pressure equalization as you descend.
