I bought this coat for my daughter for next winter. But she couldn't wait to wear it .With the adjustable wrist straps and longer length it works even if it's a bit big on her .She stays plenty warm in this unseasonable cold weather we have been having. But when it does warm up in the afyernoons she gets to use her favorite feature, the backpack straps. She loves to be able to take her coat off and not have to carry it but wear it like a backpack. I was a little worried when I first received the coat because it is so light weight, but I read up on the Shimmer reflective tech. That reflects the body heat back at the body and had my daughter try it out on a 30-40 degree day and she got way too hot by the afternoon(40degrees) so I think it will do great. And she loves it.
