The Warwick RST NB1CE B is a unusual belt for your guitar or bass. I'd orderd this belt, because my bass at this time was very heavy and my old belt gaved me back pain. Because of his wide, this belt spread the weight of your instrument over a great surface.
The belt is made out of polyester, but the cuffs at the ends are made out of leather. This could be a problem if you're vegan und don't want animal products at your equipment.
The buckle to adjust the lenght of the belt is solid and doesn't seem to break in the foreseeable future. In the end this is a very good belt for your heavy instruments!
This strap is pretty wide and even thoug Warwick Basses are well balanced and not the heaviest, still the strap is extremely comfortable. I used mine together with some straplocks and this give an extremely pro performance and your Bass will not move from your shoulder on stage. Only negative point is that this might not be the most RnR cool strap...
