mares apnea infinity 30 wetsuit: The Mares Apnea Infinity 30, of 3 mm thickness, made with shapes and cuts in two versions, men and women, is a one piece wetsuit, with separated cap, made with Outdoor apnea in mind. The materials and shapes used permit great comfort even in positions of great extension, as when diving in the typical position with arms stretched above the head. This is possible mainly thanks to the internal lining of the neoprene, called Ultrastretch, used in the areas of maximum tension, such as underarms on the side of the thorax, the base of the rear zip, and, to obtain maximum comfort, on the neck and the lateral panels of the separated cap. Compared to traditional linings, the Ultrastretch is modified both in the material and the weaving, to obtain maximum elongation in all directions. Moreover, the neoprene used, characterized by high resistance to tear and squeeze, and also elevated thermal comfort, has a specific superficial treatment, where the external smooth surface is not vulcanized, but made with polyurethane.
