The Cressi F-Dual is a single-lens mask featuring a unique assembly of lens and skirt without a frame. The mask design bonds a high-grade silicone double-feathered edge skirt directly to a single CE approved tempered glass lens for the ultimate in simplicity. The silicone facial is assembled directly on the glass without the need for a frame. This system guarantees good visibility in all directions. The low internal volume allows for effortless clearing and the quick-adjust strap buckles are molded directly into the skirt for a flexible fit and reduced drag. The Cressi F-Dual mask has a wide split strap design for comfort and to give even-tension on the skirt for a proper seal. The F-Dual Mask has an easy access nose pocket that can be used with one hand for proper ear equalizationeven when wearing thick neoprene gloves. Mask is available in multiple color choices with the opaque version eliminating reflective light found with clear silicone mask skirts making them excellent for photography or underwater hunting. Mask comes with a protective mask box.
