We believe everyone is an athlete from day 1, and this coverall is for when you want to wrap your little athlete in cozy comfort. It's made of cotton/poly knit fabric that feels soft and gentle on baby's delicate skin. The tagless crewneck provides a comfy feel and the full-zip closure makes changing and dressing easy. For extra warmth, the long sleeves have foldover mittens at the cuffs and the footed bottom helps keep tiny toes toasty.
