This footed sleeper has been named a 2013 National Parenting Publications Award (NAPPA) Honor winner, recognized for its innovative design of easy dressing zipper footies, made of silky soft bamboo fabric. This zipper opens from bottom to top. When mom changes diapers, baby’s body is still covered without completely opening the zipper. Bamboo fabric features are super soft, breathable, absorbent, and hypo-allergenic. (No grips at the bottom of feet)
