The Big Eyes mask gives 30 degrees in all directions, a very wide field of view, compared with traditional masks. It has two tempered glass lenses and is a low volume design. The mask has a silicone double feathered edge skirt that is hypoallergenic, soft, and comfortable. The profiled anatomical frame is streamlined and sits so close to the face that it seems to disappear from view when the mask is worn. The mask strap is a wide split strap, designed for a better fit and added comfort. The mask has an Easy-to-Reach One-Hand Nose Pocket for Ear Equalization which can be utilized even when wearing thick gloves. To protect your mask when not in use, it comes with a hard plastic protective mask box. The mask is covered by a 12 month limited warranty! The Cressi Big Eyes mask is commonly used for Open Water Diving, Pool, Recreation, Snorkeling and more. The Cressi Big Eyes mask does not fog, has high lens quality, a wide range of vision, and a comfortable, yet snug fit.
