I like bowquivers for most hunting but backquivers are fun to use, too. Fur along the opening makes a nice-looking quiver...I like rabbit fur because it looks good and is lightweight, available, supple...and cheap. I agree with earlier comments that softer leather that conforms a bit to your back is the best for a hunting backquiver. If you attach the fur only at the top near the opening so that it can hang down the outside for 6" or so you can tuck the hanging portion loosely into the opening around the shafts (fur in) to reduce noise/shaft movement when hunting. When ready to draw an arrow for a shot simply give a little tug on the fur to lift it out enough for the arrow to clear. When not hunting flip the fur back to hanging on the outside again.
Easy, quiet, and if you move slowly there is little movement involved.
