My eight year old daughter is a nut. She likes to wear tights like these and then jump from the couch to a pillow landing on her knees. Something about the texture. She is autistic so sometimes I do not get to know the answer. During the winter I bought a few of these to keep her warm and found out they are also much more durable. Now it's all I will buy. Wish they were a tad longer for her long skinny legs. But otherwise very happy.
