The coziest jammies ever! Dress your toddler in the same soft and stretchy bamboo viscose as our Zippies, but in a two-piece set that’s easier for potty training. Featuring long sleeves and matching long pants, our two-piece sets are designed with extra length so they’ll fit longer than the average PJs. Caution - We have a baby builder on our hands! Tractors and utility trucks sit upon a white background with sky blue trim. This pajama set is perfect for the little one who wants to be an "engineer" when they grow up!
