The Williamson Vortex Speed Jig is one of the most innovative, versatile jigs on the market today. The hydrodynamic design with opposing convex & concave sides allows the jig to rotate effortlessly on the fall. The rotation combined with the two-sided color pattern creates maximum flash that drives fish crazy. Each jig is pre-rigged with a stainless steel ball-bearing swivel and a single VMC Assist hook.
