KIFARU Shape Charge on a FRAME || My HYBRID Saddle Hunting Backpack. In this week’s video, I walk you through how I set up my Kifaru Shape Charge on a Kifaru Frame to build my new Hybrid saddle hunting backpack setup. The Kifaru Shape Charge is the best whitetail hunting backpack that I have used over the years, but with more out-of-state hunting trips, there was a need for a frame pack to haul out meat. This setup allows me to transition from the Shape Charge on a frame to the standard configuration when the frame is not needed very easily.
