Just great! The information in Tox are super! We have so much tried. Our 3-year-old daughter has always complained that it freezes. Since Slumbersac those days are gone at last and she sleeps great! Although it does not contribute as recommended only a body, but pajamas, socks and body, but we can finally sleep at night! Can only recommend the product. We've tested a lot of sleeping bags, but these are the best! Value for money is great!
