My dad has the Catquiver I and swears by it. I've been wanting to buy one as I remove the quiver when I get to the tree anyway. I've been looking at the Catquiver II and III as I need a little more storage room. That way I can lose both the backpack and the quiver. My dad's Catquiver I seems very well built and he's had it for about 7 years with no problems.
