dBb Remond Crumb-Catcher Bib is a large bib in jersey, covered with transparent printed plastic, for food to slide and not to put dirt on the fabric.
It has a harder plastic crumb-catcher, which can be fastened by pressure buttons to make cleansing easier and to put on or not, according to your child's age.
The crumb catcher prevents the child from putting dirt on his pants, which is very often made with classical bibs, even if they are large. Once food has been collected in the crumb-catcher, you can just throw it away.
The crumb catcher fixes by Velcro behind the child's neck, for more manageability.
