With the ability to mix and match pieces, divers who choose one of these classic two-piece suits will discover they have several options for thermal protection on every dive. Worn together, the John and Jacket system gives a double layer of protection over the body-s core for the coldest conditions. For warm waters, wearing just the Step-in Jacket provides essential core warmth while maximizing mobility. Glued and sewn seams in the thicker suits provide toughness and water integrity, while flatlock stitching in the 3mm is durable and comfortable. High-quality zippers in the jackets and Velcro-style shoulder entry in the John and Jane insure simple donning and prolonged suit life. Pieces are sold individually or in sets so divers can mix suit thicknesses.
