Made of strong but stretchable X-Foam neoprene with a tough UV-resistant and chlorine-resistant 2-sided polyester lining, this 2.5mm shorty is perfect for tropical diving or pool sessions. Anti-abrasion material on the shoulders and seat area shield against chafing BC straps and non-skid boat seats, greatly extending the life of the shorty. This is an ideal dive suit for diving classes or resort use.
