Cressi Calibro + Corsica Professional Mask and Snorkel | Green | One Size The new Calibro mask with Corsica snorkel package is ideal for all your snorkelling adventures. This mask and snorkel set is light, durable and features anti-fog properties for clearer vision when in the water. The mask is equipped with IDF-INTEGRATED DUAL FRAME TECHNOLOGY which offers an exceptional field of view. The mask is designed so that the integrated face and frame allow for an extremely hydrodynamic and compact shape and a particularly wide lens, maintaining the mask extremely close to the face. It combines minimal internal volume with a phenomenal field of view due to the raked angle of the frame. The buckles are 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. With the matte coating the masks components all match, enhancing the underwater experience since it prevents reflections in the water that may disturb marine life. It is the perfect mask for free-diving, designed to provide the diver with a feeling of total freedom and comfort. The mask further features a patented membrane surrounding the inner nose pocket which acts as a barrier and traps any moisture escaping from the diver’s nose involuntarily when breathing through the mouth. The result is that not only is the moisture channeled away from the lenses, thus avoiding the fogging up of them, but it also reduces the need to compensate for pressure. The snorkel is a highly technical, designed specifically for deep free-diving and spearfishing. The soft bendable large diameter tubing makes it extremely comfortable to properly position behind the head while maintaining ease of breathing on the surface. When diving, the mouthpiece tucks neatly under the chin for the ultimate in hydrodynamics. The anatomical hypoallergenic silicone mouthpiece provides extreme comfort during long durations in the water.
