Got size small for a small 7 year old boy and it is a great fit. Easy for him to do zipper on his own. Doesn't bunch up much when sitting in car. The amount of insulation is perfect. He can wear it with just a long sleeve shirt on cool days, but add a hoodie on colder days. Seems to be very durable. Received with in a few days of ordering.
This is the 2nd Columbia coat of this style that I've purchased for my son. He loves them! They keep him warm in the coldest temperatures, but aren't extremely bulky either. The first coat he wore for two years, and it held up very well to the wear and tear an 8-year old boy will put on a coat. I would highly recommend buying this coat.
