I read reviews that the sizing may be a bit "off" but we had just purchased a Columbia snow pant and jacket set in a 2T and it was a little too big.  So since that was our first Columbia purchase for our son, I thought that perhaps for him, 2T ran a little big.  So we ordered the 2T and it fits great, but he probably won't be able to wear it next year.  Bummer.  It's an adorable pattern and the fleece is like a blue/gray.  I thought it was going to be black, so it was a pleasant surprise.  It's a great coat, he stays warm (or warm enough to not complain - he doesn't talk yet so he can't tell me if he's cold) and it's easy to zip.
