This is a great hoodie. My son is 22 months and slightly bigger than average (65% on growth chart) so we sized up and got the 3T. I'm so glad I did, as the 2T would have been way too small. Despite the initial confusion over sizing, ordering was easy and delivery was fast. After seeing her brother's hoodie, my older daughter wanted one and loves her's just as much!
We love these. They're a perfect balance between sweatshirt and jacket (although more on the sweatshirt side) -- just right for when a typical kids sweatshirt isn't quite enough, but a warm jacket would be too much. They're super, super soft on the inside and my kids love to wear them -- they'll actually wear them voluntarily! They stand up to washing (and the abuse that kids can give their clothes) very well. We probably have a dozen of these at this point -- in sizes from 3-6 months up to 3T, and in green, brown, orange, red, navy and light blue. And, they're really cute.
