I purchased these for my son and daughter for Christmas and ordered the matching adult 2-piece sets for my husband and me! THEY ARE great. My kids continue to wear them long after Christmas. They don't sleep in them as they are incredibly warm. But, they do throw them on over Pjs or undies on cold mornings and wear them as "loungewear". Unless your kiddos normally sleep in flannel, these may be too warm. My kids traditionally sleep in cotton pajamas. But, they have been perfect to throw on once they are up or to add for a movie night. Both kids say they are comfy and super snuggly.These are cute and have held up surprisingly well in the wash. I didn't have high expectations since they are so affordable! I have washed them 10+ times! And, they still look great and are soft. My son asked for another one to wear so he always has one available!I found them true to size for my kids, too. (My husband and I don't wear our matching set often, but they were perfect for a festive fun Christmas!)
