This is a gray, fleece-lined, cold-weather down cover that can be attached to a baby carrier. It attaches to the carrier with snap-button loops. Your baby will be perfectly warm even in winter. It has been confirmed to fit an Ergobaby carrier. It should likely fit other brands as well, as you just need to thread the loops through the shoulder straps, but please be aware that this has not been confirmed. By the way, even after your baby has outgrown the carrier, it can also be attached to a child seat on a bicycle and was very useful in winter. (Please note that it may not be compatible with all child seats.) It has pockets to keep your hands warm. - Color: Gray - Material: Polyester, water-repellent finish - Lining: Fleece - Brand: Baby Hopper
