True to size and soft
I initially thought they were too small but when they tried them on they fit perfect, but I do have skinny kids. They immediately loved them and said “these are so soft” and asked to wear them for the rest of the day.

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.

Decent
Decent base layer. The top is too short for my son but he is tall. Bottoms fit fine.

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.

Its not a set as has been vaguely mentioned in the product description. As other reviews mention, its only the top that they send. Disappointed.
