Review on Navy Boys' Clothing and Active: Boys' Thermal Long Underwear by Scott Channell

My 10 year old son is thin and slightly above average height. He doesn't have clothes larger than 10-12 sizes, but based on reviews I ordered 14-16 sizes larger. They're a bit baggy on him, which I can live with, but the sleeves are still a bit short, which is a problem. They only seem to be made for small or slightly chubby children.
