The Big Eyes mask gives a very wide field of view. Compared with traditional masks, it increases the field of vision 30° in all directions. The Big Eye Mask has 2 tempered glass lenses and is a low volume design. The mask has a silicone double feathered edge skirt that is hypoallergenic, soft and comfortable; making this mask fit a wide range of faces. 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. Its extraordinary inverted teardrop lens visibility, together with extreme comfort, efficient adjusting low-profile buckle system for the silicone strap makes this model a great choice for all diving activities, from snorkeling to deep free diving, to scuba diving. The mask strap is a wide split strap design for a better fit and added comfort. 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 the Big Eye comes with a hard-plastic protective mask box. The Big Eye Mask is available in multiple color choices.
