I was looking for a fall/spring jacket for my 6 year old that would also work as a raincoat. This jacket is perfect for that. It has a fleece lining at the back, front and hood, and a double layer with some filling in between in the sleeves. I got a size L/6x for my 6 1/2 year old who is slim built and average height. It fit her perfectly, with some room to grow... except that the sleeves need one fold, which is ok. It has very cute design details in the pockets and a cute little heart.
