These fun, comfortable cotton pajamas make the perfect addition to any jammie collection. These jammies are 100% cotton, soft and comfortable for your little dinosaur lover. Pants are pull-on with wide elastic waist band, and the top and pants are ribbed at the waist and cuffs. Both also have a tagless label for your child's comfort. The fit is super snug so you may need to go up a size or if your child is on the cusp of going up a size soon, you may want to go up two sizes.
