I've a bad back and play bass, at times for hours on end.
This strap makes it a lot easier, compared to the "usual" nylon strap I have on my other bass.
A small thing - I wear the bass pretty high, and the Short strap was still a bit too long for me, and zero room for further adjustment. Got around it by folding and tying the nylon section a bit shorter, so not a real problem in the end, but keep in mind.
