Aramid fiber (DuPont™ Kevlar®) reinforced fabric covers the whole suit and an extra protective layer is added on the knees pads. As standard, the SF Tech Neoprene PRO comes with a front entry zipper and telescopic torso allowing the diver the to be self-sufficient in the donning and doffing process. The fold of the suit is held in place by a crotch strap.
