NY Built has been using wetsuit material for their products for several years, and have found it is perfect for waterproof baby bibs. The Built NY Comfy Bibs??? (0-1 year) and Tidy Bibs??? (1-2 years) have an absorbent, soft and machine-washable surface, and a waterproof inner layer that keeps moisture from seeping through. The Built NY Tidy Bib also has a crumb-catcher that is held in place by velcro tabs and can be undone for easy cleaning.
