Yeah, Chad, most back quivers you get these days are made with leather that's too stiff and will definitely dump your arrows when you bend over. Softer leather will bend with your back and actually clamp the arrows in so they can't fall out, so keep that in mind for when/if you decide to make your own.

My beef with back quivers is I'm so tall I already have a problem with low hanging tree limbs and the arrows don't bend with me when I bend my head. My head clears the branch but the arrows bring me to a dead stop. [:@]

I've come to like the Plains Indian style quiver. It hangs by your side where you can grab it and hug it into your chest while going through the thick stuff. It doesn't take a whole lot of movement to draw an arrow. I didn't put one on mine, but you can add a flap to the quiver to fold over and protect your fletchings if you get caught in the rain. Mine cost me about $10. Found the leather for cheap in a flea market.
