This is a PETIT BATEAU sleep sack. Size: 0-6 months Color: White x Blue x Floral Thick, with padding. TOG 2.0 My daughter used this from about 1 to 5 months old. There is some fuzzing of the fabric and wear on the zipper. There is discoloration on the shoulder area! Please check the photos. Made with high-quality cotton, it's gentle on baby's skin and provides a comfortable feel.
