This may well be due to a brand or size issue. I would not abandon bibs based on one experience with them.
I haven't given up totally on the idea of bibs, but due to the first, not so good, experience that I had with a pair that I borrowed, it isn't on my list of things to do in the very near future. At the price that a decent bibs go for, it would get pretty expensive to try several pair only to find out that I don't like any of them.
