We've purchased these bibs several times. Originally they had a snaps at the back of the neck, making the bib both secure, and adjustable by a small amount. Now, they have velcro fasteners, which don't allow for much adjustment, but worse, they wear and become unravelled after a few washings, rendering the bib useless. This is a cheap downgrade, passed off as a convenience upgrade. To the seller and manufacturer -- go back to using snaps at the neck, they are both more secure, and better quality.
