We all need at least 2 pair of Fleece leggings in our lives. On the cold days when your kids need some fresh air and you know that those legs will be cold but you agree to go outside and supervise your kids while they play with their new toys from Santa.....fleece leggings are just what these cold days call for...and a cup of coffee as well!!! These are OS and fits sizes 0-10/12. Don't get left out in the cold...without your fleece!!
