This zip one piece is super soft and comfortable. Featuring a zipper that runs from the top of the outfit to the ankle. Our favorite part about this outfit is that the zipper is 2 way! Making for super easy diaper changes without having to remove the whole outfit. The fabric used is super stretchy and breathable, made from bamboo viscose, wait until you feel how soft it is! These run about one size big leaving room to grow but are meant to have a slim fitted look to them.
