GUD size 4T Burton Toddler One Piece Suit in Snow Day Print. Slight signs of wear but in great condition, wish we could get another year out of it! The Burton One Piece is adorable. Look at that little tiny removable hood and little sleeves. It's super waterproof and packed with enough insulation to keep your little nugget toasty warm and give them just a hint of that waddling marshmellow look. This one piece was specially designed to provide the highest possible performance for making snow people and sliding sideways down the bunny slopes with all giggles, no tears.
