They fit well and the kids like them.
Bought these for my nephews for both layering pieces and winter pajamas. The kiddos like how soft they feel and they wear them all the time.

Cozy for winters
So warm and cozy, my son loves it. Great to wear as a base layer in the winter. My son loved it so much I had to buy another. Yes, it does pill. But i think it's because the fabric is thin. Serves our purpose well.

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!

Perfect for Skating and Sports
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.

Good quality
Bought this set for my son to wear under his soccer uniform. He says it’s very comfy and did a great job at keeping him warm and dry while playing in the rain without getting too sweaty. Washed well. Would buy again. We bought a size up and it fits him well with a little room to grow. If your child is tall or a heavier build, buy the size up.

XS Warm and fits fairly well
Bought XS for our 4.5 year old son - kept him warm, waste was big on him but not a big problem since it goes under his clothes so top layer helps keep them up. Good quality and washes well so far
