Developed to allow you to create ‘ultra stiff’ rigs, Rigidity can be straighte­ned easily between your thumb and forefinger to form perfectly straight hook-links ideally suited for the presenta­tion of pop-up baits in conjunction with Fox's Se­ries 6 Stiff Rig hooks. Extruded from clear polyester, resulting in a low visibility material, which is hard to see by fish, even in clear water, Rigidity is the ultimate stiff rig material for today's carp anglers!
