The frameless masks are loved by many snorkelers for their low-profile and comfort. The Mini Frameless is the kids' version of the popular Cressi F1. The mask is commonly used for open water diving, pool, recreation, snorkeling and more. The Mini Frameless mask design bonds a high-grade silicone double feathered edge skirt directly to a single tempered glass lens for the ultimate in simplicity. 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 easy access nose pocket can be used with one hand for proper ear equalization and the single lens design affords a wide field of vision. The mask has a wide split mask strap design for comfort and to give even-tension on the skirt for a proper seal. The mask is popular since the customers like the following qualities of the Cressi: does not fog, high-quality lenses, a wide range of vision, snug fit. The Mini Frameless is designed in Italy by Cressi and made in Taiwan. Cressi is a brand pioneer in scuba diving, snorkeling and swimming equipment. Safety Warning: do not dive head first into water while wearing the mask to avoid the possibility of causing any injuries. The lens exceeds the impact test requirement of American National Standard Z86.11-1985.
