planet waves sells a comfy bass strap (specifically for bass players) it's thick and padded...the one you linked (Levi's) does not work if you wanna use strap-loks, the leather is too thick.

Personally, I prefer the Comfort Strapp, but you're looking for leather, so that eliminates the Comfort Strapp.
