The freedom one mask features the newly developed and revolutionary freedom technology delivering superior fit, comfort and performance. Each person has a unique facial structure and every diver can potentially experience some level offort or pressure while wearing a typical mask underwater. Freedom technology delivers superior fit, comfort and increased performance through a dimpled skirt, varied silicone thickness, and stability ridges. Dimpled skirt: key areas around the forehead and cheek bones have been designed with dimplesbine to increase the skirt’ s softness, flexibility and skin surface contact. This also greatly reduces leakage andfort. Varied silicone thickness: a regulator or snorkel mouthpiece, when in use, can cause areas of the mouth and nose section to distort causing leakage andfort. Varied thicknesses of silicone in these key areas reduce leakage and provide a better fit. Stability ridges: as water pressure increases, a maskpress inwards toward the face, often causing further leakage orfort. Areas under the cheek bones have been reinforced with stability ridges to minimizepression maintaining ideal skin surface contact. Features: low profile, low-volume 2-window teardrop design equipped with freedom technology skirt mounted quick-adjust buckle system round-edge skirt for maximum fitfort 3-d strap for ideal anatomical fit
