Ruby Wrapp Bibs are waterproof. Waterproof bibs are perfect for keeping your child clean during mealtimes. The soft, durable fabric is made to last, and the waterproof coating keeps food and drool from ruining clothes. Our bibs can be easily machine-washed in warm water. Do not machine dry. A convenient addition to any mealtime routine, Ruby Wrapp is made of durable silcone that can easily be wiped clean, so you don't have to worry about spills and stains. Plus, they're adjustable to fit most sizes, so your little one can wear them comfortably.
