These are Brannan Bear pants purchased from GAP. They are fleece-lined, so they are recommended for the cold winter season. I have only worn them for one season, so there are no noticeable stains, dirt, pilling, or tears. Please understand that these are used items before purchasing. I am also selling other outgrown children's clothes. If you would like to purchase multiple items, please write in the comments, and I can offer a small discount and ship them together.
