I purchased this from Sweet Mommy for 26,784 yen. It can be used from maternity to postpartum. It was so convenient because it integrates with the mom's down jacket without having to put a coat on the baby! There are no gaps, so it's really warm! The down is also firm and warm. When using a stroller, you can remove the duster part and use it as a blanket, and the mom can wear it alone!
