I'm a tall guy and this still fits well even though the straps are on the first hole. The metal ring at the bottom is ridiculously small and even if it would fit I would be wary of putting a metal ring there. I bought a rubber ring online, some rivets and a hole punch for $20 and was able to replace the small metal ring with a large rubber ring in about 2 minutes.
