AirBuggy footmuff. I received this as a gift 5 years ago. Outer fabric: 100% nylon Lining: 100% polyester Filling: 50% down, 50% feather I used it with an AirBuggy stroller. I used it every day in the winter, so the fleece lining has some wear. I always took my shoes off when using it, but the foot area is particularly fuzzy. For those who understand that this is a used item. It's very warm! I will compress it for shipping, so please forgive any creases.
