This cap is extremely comfortable and it fits my 24" head, which is much larger than the average head.  I also love the color.  It is soft and even though my head gets hot, particularly when I sleep, the cap does not make it worse.  However, I would caution buyers.  There is a tag sewn into the hat, larger than a postage stamp I'd say.  I very carefully cut it out but because it's sewn into one of the seams it left about a one inch hole.  I will have my mother sew it and continue to use it.  However, being on chemotherapy and having lost my hair, a large scratchy tag is unacceptable because my scalp is extremely sensitive.
