I’m too much of cheapskate to buy dribble bibs. I got a metre of fleece in a colour I liked and cut it into bib shape with long bits for tying. Or you can be more industrious and sew poppers on. I really didn’t need a whole metre. If I had sewed popper on, I probably could have bought 25cm and made 5 using the width of the fabric. It worked really well. I had to keep several with me, but the cost/effort factor made that worth it.
