Enjoy all the views of the underwater world with this wide field of view, single lens scuba mask from TUSA. The Freedom Elite uses several technological features to improve comfort and function. Freedom technology enhances the comfort, fit, and performance of your scuba mask by dimpling the mask skirt and varying the thickness of the silicone. Stability ridges paired with the low-friction mask skirt surface improve comfort on the fitting line. A 180° buckle system rotates to fully adjust to all head sizes.
