This revolutionary evo mask is made from High Seal, a new material that offers extraordinary and unprecedented comfort. Not only has this new High Seal silicone been chosen, with its exceptional softness and comfort, but the entire design of the skirt has followed new rules which allow a point of contact between the mask and the face that has a very open angle. The mask rests on the face with unprecedented comfort and does not leave any marks on the skin, even after extended use. Naturally, to obtain such a result the entire structure of the skirt is differentiated, with internal ribs that stiffen the parts of the mask that are most stressed. ............................. Palau opens the way for a new type of snorkelling and swimming fin. In actual fact, it has been designed for two specific needs. The first was to have a foot pocket that could easily adapt to at least three or four consecutive sizes so that the same fin could be used by all the members of a family, or by a group of friends or easily rented out in a diving centre or on a charter boat, without requiring an infinite number of sizes. ............................. Profiled guard: this drastically reduces water intake and splashing from the top without blocking breathing. Adjustable attachment: system of quick-attachment to the mask strap, which runs along the snorkel bore for perfect positioning. New drainage well: this draws all the remaining water to the bottom end of the tube, preventing all blockage to breathing. Internal elliptical valve: the elliptical valve optimises water drainage, making it quick and easy to purge the snorkel.
