Beautiful cotton rompers in darling prints for your little ones. Four options for you to choose from. For baby's sensitive skin, extra-long-staple Pima is the world's softest cotton and it breathes better than bamboo rayon and other synthetic materials. Unlike short-staple cotton and bamboo, Pima cotton will never pill and will stay forever soft. When it comes to the impact on the environment, the surest way to make a difference is simply to buy less. One way to make that easier is choosing only high-quality clothing, made from natural, long-lasting fabrics—such as Pima cotton.
