BABYHOPPER Baby Carrier Winter Cover Retail Price: ¥13,000 Filling: 90% Down, 10% Feather I didn't want to use strong chemicals or detergents on my baby's things, so when I had it cleaned, I used a cleaning service that uses additive-free soap. When I washed it at home, I used negative ion water, bamboo detergent, and a laundry magnesium ball. I think it's safe for babies ☺︎ It's quite warm with 90% down, and the inside is also fully lined with boa fleece, so it was very useful in the winter. It can be used with a stroller, and my baby could nap comfortably outside☺︎ It has pockets, so my hands were warm too ⭐︎ Winter cover, carrier cover Ergobaby Winter Multi Down Cover
