I'm not into the bright colours, just a plain black Adidas golf canvas belt for the course.
I first thought you meant "golfers belt" like a builders tool-belt. Now that would be neat.
Little loops for your tees, a magnetic bit for ball markers, a couple of suction cups for spare balls. A pouch for your range-finder. A little flip-down cup/bottle holder and a hook to hang your brolley on.
I'm off down the patent office - I think I've just found the way to my fortune.
