This sleeper from Kickee Pants is made from silky soft bamboo. It features folder over cuffs, gripper soles, and neck-ankle snaps down one leg for easy dressing and changing. The tag on the sleeper reads nb and fits true to size. Since this was one of our favorites and worn frequently, I have listed them as GUC. They were, however, delicately laundered and never dried which has helped retain their softness and quality. There is a little pilling but no stains or major defects. 95% viscose from bamboo, 5% spandex.
