Softest organic cotton jersey. Two buttons per strap for growing kiddos. Organic cotton striped lining on bib. Sizes 0-24M have a three-snap bottom closure for quick changes. Sizes 2-5Y have a pocket on the bib for treasures. Pair with Max Raccoon for a matching gift, or purchase our doll-sized overalls separately so any kid and any animal can match. We've received some feedback that the fit of this kidswear may run small, so we recommend sizing up for maximum coziness!
