Covers baby from neck to ankle, made of waterproof material for keeping baby clean and dry. Fastens over the shoulder and around the waist for comfort and safety. And fastens around the legs to keep it in place giving baby freedom of movement. Never has there been a baby bib with this much coverage or one that stays in place as well as the baby chap. The chap is great for feeding time, when baby starts teething, preventing unsightly stains we all had to deal with in the past.
