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!

Soft but not long lasting
Super soft and comfy and let my son warm in the cold while he wore these as thermals or undergarments while skiing. Unfortunately, how we. They already-appear to look quite worn after just one wash

My son loves these, they are light and breathable, yet warm. The material is exceptional, and so far has not shrank. My child uses these for skating and hockey. We used to layer up with pajama pants, but this is much better. Coincidentally, these can also be used as pajamas. * They are comfortable. * They are breathable. * They do not shrink.
