1. The fake two-piece design is fashionable. The loose-fitting onesie will not restrict the baby's limbs. 2. The body is made of magic stretch yarn fabric, which is a combination of combed cotton and plant-extracted SORONA fiber, so that the fabric has a bio-based spring structure (not spandex, with good shape retention). The sleeves are made of thick ribbed fabric with a layer of sanded surface, which feels softer and warm to the touch. 3. The cute kangaroo patch pocket can hold baby's snacks and toys, which is cute and adorable.
