Wow, these pants are legit. I got these for my 10 year old daughter and she absolutely loves them. We keep our house pretty cold during the Winter to save on heating oil so we try to bundle up and opt for clothes that offer extra insulation. These sweatpants are perfect for keeping her warm.The inside is lined with a fleece like material that looks and feels like lamb wool. I don't believe it is real wool but it is extremely comfortable nonetheless. I am quite jealous and wish I had a pair like them for myself. The quality of these sweatpants is outstanding and the material is nice and thick.I do have to say that I believe these pants are a little on the large side. The tag says they are for children ages 9 through 10. They swallow up my 10 year old daughter and are long. As you can see in my picture, these go past her feet and she steps on them when she wears them. I would recommend ordering up a size. Normally, I would remove a star from the rating because of this but these pants are so nice that I still wanted to give them 5 stars.
