I have searched on 'wide straps' and on 'leathercraft', and not found any reference to Leathercraft straps, so I thought I'd let you know. Leathercraft (in Liverpool UK phone 0151-734-4740) has no website, and no email, but make a 3 3/4 inch (95 mm) wide strap with a soft leather outer skin, neoprene core and suede underside. The back end of the strap is conventional 'loop through the slots' levi-style adjustable 1 inch leather strap. I have one on my first bass, and wanted a second one for my new bass, but it took some finding. Sound Control in London, Oxford Street (basement of Virgin records) had some in stock, but I do not know if it is going to be a regular line.
