This auction is for 1 Kydex insert. It is .060 thick to give rigidity but not too much weight. Works like a charm. Makes sure your pack doesnt sag or bunch. I made one for myself and after popular demand, I handcut them for sale. My pack is not included but some people asked me about my mods so here they are: Maxpedition shoulder pads. Velcro addition to hydration pouch. Shock cord. Carabiner. Clip on light. Austrialpin buckles.
