I bought this sleeping bag after reading reviews on many other youth sleeping bags. First, can't beat the price. My daughter is 8 and slightly tall for her age, so I'm not sure how long she'll fit in it, but for now it's perfect. When she does outgrow it we can use it as an extra comforter to lazy-around in. She loves it and has slept in everyday since she got it....sometimes on the floor, sometimes on her bed. It seems very well made and very soft and warm. I don't think we'll ever test if if keeps her warm to 25 degrees. It will mostly be used for sleeping indoors and in our camping trailer. Nice sleeping bag.
