I've had a Cat Quiver, and it's a great concept, but it's definately not a "one size fits all". I gotmine from a friend, and after I tried it let another friend try it. All three of us are big guys (over 6' tall) and broad across the shoulders. It wasn't comfortable for any of us, and with it sitting in the center of your back it was a pain to get an arrow out, and a real pain to get an arrow back in.
