Super Fly's exclusive sticky rubberized fabric is even more viscous than the Nemesis. A removable, reversible outer flap was added to even further disguise the firearm. This pocket holster will absolutely not move out of position in your pocket. The inside is made of slick pack cloth for a low friction draw and is reinforced with added polymer in the right places. Back or front pocket design.
