I ordered a 3T for my son, who'll be 3 in March 2013. The material is nice, you can't beat the price, not to mention how hard it is to find turtlenecks for toddlers. I've been looking for it all winter, apparently all the major kids' brands don't make them any more. The only complaint is that the neckline is way too narrow, and my son's not a big head boy, his head size is in fact a little below average at his age, so I have to squeeze him in, and he thinks it's a funny thing to do. Wish I've ordered one size up for him.
