Our baby sleeping bag in dark blue is made of cotton for a comfortable and healthy sleep. Embroidered on the front with the inscription "Sweet Dreams." The sleeping bag has a two-way zipper at chest height, making it easier to put on. Additionally, the zipper is separable, allowing the bag and vest to be quickly detached from each other. Additional tie straps on the vest part ensure a perfect fit for your baby, preventing any twisting. The entire sleeping bag is padded and lined on the inside, so there are no annoying seams.
