My daughter loves these as a base layer when she goes horseback riding. The barn is super cold and these help to keep her warm but are comfortable so she can move around and care for the horse and ride.
Warm,comfy, can easily be worn as a stand alone or under other clothing; perfect cold weather wear.
My 8 year old daughter loves the thermal sets. She wears them any time she is in the house, night or day. As soon as she gets home from school she immediately changes into them. They are so soft and stretchy, and fit true to size. We have 3 pair and will be purchasing more.
This is our second pair, and we got it because my daughter was wanting to wear her initial pair every day (!). Needless to say, they are one of our favorite clothing items this cold, snowy winter. I am sure we'll be back for more.
Form fitting but comfortable, not overly tight. It should be snug to actually keep you warm.
