Thank you for visiting! ( *´艸｀) These are very helpful when you're out and about with your baby, whether you're carrying them, using a baby carrier, or a stroller (*^^*) Perfect for taking your baby out on cold days! These are all handmade. The fabric is fleece, and this is a set of three pairs in: Nordic Red Nordic Pink Nordic Brown Please note that we cannot exchange for other types or colors <(_ _)> The inside is fleece, so they are very warm, and they fit up to a foot size of about 12cm. Please be aware that these are not for outdoor use.
