The buckles are, as always, directly integrated into the rigid skirt through a solid but flexible rubber attachment that allows you to adjust and place the mouthpiece without shifting the mask. Thanks to its matte coating the dive mask’s components all match, enhancing the underwater experience since it prevents reflections in the water that may disturb marine life. Calibro is the perfect dive mask for free-diving since it is designed to provide the diver with a feeling of total freedom and comfort.
