Great thermals!
I got these for my son who’s 4- he wears them under his rain and snow gear at nature school all day and it seems to keep him much warmer and more comfortable than regular shirts and sweats. I didn’t notice any shrinkage but I have found that they pill quite a bit especially when used as under clothes. The patterns were exactly as they were advertised and the size guide seemed to be great gage of what to purchase!

Sizing off, warm and soft
I bought two pairs. One for my 4.5 year old and one for my 2 year old. I bought an XXS for the 2 year old and a S for my 4.5 year old who is tall for his age. He wears a 5-6 size. In both sets, the shirt fit as expected but in both sets the pants were two sizes too big. The XXS pants could fit my 4.5 year olds waist but definitely too short. I was able to take a thread and tighten them so that when they do grow into them (hopefully next season), they’ll fit and I can clip the thread. For the price, I would expect the sizing to be correct. They are warm and very soft and I love that they come in patterns to appeal to kids instead of solid colors like most thermals.
