It revolutionized scuba diving. A direct descendant of the "Stab" Jacket, the CLASSIC combines the best design and construction features of past and present. Built with puncture-resistant polyurethane-coated 420 denier nylon, the CLASSIC's seams are RF welded for maximum durability. The BCD comes with a stainless-steel Super Cinch tank band system, a quality web waist belt with stainless steel cam buckle, large pre-bent stainless steel D-rings and one of the most secure and reliable integrated weight systems around. Built tough, armed with a first-class valve system and offering outstanding buoyant lift, the CLASSIC can handle any job, anytime. It's the original, and still the best. "
