This coat is very warm, and excellent for a little boy to run around in outside!  I ordered a 2T for my child who is currently between 18mos & 24mos sizes in clothing.  It fits a little big, since he is not a true 2T, but is perfect for when he wears bulkier shirts or an extra jacket for more warmth underneath.  The size is great for him to grow into (hopefully for next year as well.)  The ONLY thing I dislike about this jacket is the hood is not designed well to stay on the head, even with a winter hat on.  I find this with many coats, child & adult alike.  The color is my favorite part, as most boy winter coats are black, green or grey.  This color is distinguishable, especially in a setting such as school where coats always get mixed up, or when out in public and your child wants to walk around!
