Even in warm water young divers can chill quickly, and this 3mm Jumpsuit delivers full-length protection for extended dive times and multi-dive trips. An adjustable collar seals smoothly around the neck for a non-binding fit that helps keep out cold water, and the rear back zip makes self-donning a breeze. For added protection, flexible knee pads reinforce the high-wear areas of the lower legs. Neoprene material, flatlock seams, back zip.
