Hard Shell Jigs are a metal jig coated with an exterior skin of resin/epoxy giving them a durable, translucent finish.  Hard Shell jigs cast very well due to their shape and compact profile.  The Slim Profile Hardshell, as the name suggests, is flattened in shape and tapered at the head and tail.
 
When retrieved quickly, the jig kicks strongly.  When moved slowly, the jig has a seductive flutter in the water.  Due to its shape, the jig will drop quickly through the water column when vertically worked.  All the jigs come with a reflective foil finish in a selection of colors that adds to the fish-catching qualities of the jigs.  Additionally, the eyes of the jigs are positioned behind the clear finish so that they don't fall out and don't disrupt any of the aerodynamic qualities of the jig.
