100% organic cotton at a very competitive price. These footie outfits are just right for any weather. They are made of lightweight breathable cotton fabric that is perfect for warm weather or layering for cooler weather. The cuffs and collar are trimmed in an even softer fabric for no discomfort for baby. The zipper easily goes up and down, making diaper changes a breeze. The snap at the top has a tiny bee printed on it and there is a square Burt's Bees Baby label sewn just under the collar in the back. I love the grippy bee design on the bottom of the footies that is just right for babies on the move and learning to stand either assisted or alone. Definitely recommended.
