The one item you will buy that can be used for a very long time (at least long when it comes to baby clothes). They fit with rolled up sleeves when your little one is starting solids and will fit them at least till they are 2 years old (Picture is an almost two year old). They are also great to protect clothes from messy art work.
The bibs are made out of PUL (Polyurethane Laminate), which is a water proof material also used for cloth diaper covers. They are easy to take care off. Wipe them down after eating to re-use or trow them in the wash (wash warm, do not put in the dryer).
The bib has two snaps in the back for an adjustable fit around the neck.
