This set is made with organic cotton jersey on a natural colored background. Adorable "Tater baby" graphics are designed like an old fashioned potato sack with new fashioned sensebilities. Elastic at the bottom gives just enough of a reinforcement so the sack doesn't "ride up". The long sleeves have a clever, fold-over mitten so babies can have their hands covered, so fingernails don't scratch their face. Matching hat says "spud". How cute is that?
