We love these bibs from Rain & Conker becuase they have no synthetic materials at all.  a 100% organic cotton layer on the front and a layer of soft and super-absorbent organic fleece on the back, so they are so soft on baby's skin with no harmful chemicals. 2 nickle free fasteners for a snug but comfortable fit from newborn to 3+ They washes and dry brilliantly – this organic premium line of bibs retain their shape really well even when tumble dried.
