Kicky Pants footie pajamas are made from 95% bamboo and 5% lycra.   These footie pajamas are made to fit snug.    The footie pajama feature flip paws to cover cold hands and prevent scratching.  Bamboo absorbs water 3-4 times better than cotton, keeping skin comfortable, rather than sticky.  When wearing bamboo your child will stay 2-3 degrees cooler in hot weather and warmer in the cold.  Machine wash cold.
