We have stepped up our freediving game with the Stealth mask. There is nodoubt the Stealth is ready for the Freediving and Spearfishing you have inmind. The skirt was carefully designed with Low Volume and Ergonomics at theforefront of the design. The low volume mask and reinforced silicone nosebridge were specifically created to compensate for the squeeze you putyourself and your mask under when diving deep. The low volume also provides awide field of vision for the diver.
