Review on 👕 High-Performance Subuteay Thermal Undershirts Baselayer X Large Boys' Clothing: Ultimate Comfort for Boys' Underwear by Sonny Nevers

I posted this on purpose if you are looking for gauges. My son will be 4 in October 2021 and has been wearing a 5T since January but can also do a 4 and 5 in big boy clothes. It is quite large for its size but I ordered the smallest size they offer and I have to say they are a bit long but other than that they fit him great, they are roomy enough not to be snug and he can wear them to fit perfectly When it comes to short and long sleeves, I usually put them under a sweater when he's warming up. They wash/dry great and the material doesn't change or distort in the wash/dry and I'm certainly glad we got them for him as he was away last year and going to school this year and for him Morning class in what learns.
