Genesis Stealth Mask A Freediving, Spearfishing and Ultra Low Profile Scuba MaskWe have stepped up our freediving game with the Stealth mask. The skirt was carefully designed with Low Volume and Ergonomics at the forefront of the design. The low volume mask and reinforced silicone nose bridge were specifically created to compensate for the squeeze you put yourself and your mask under when diving deep. The low volume also provides a wide field of vision for the diver.
