Love this cap, I shave my head every morning and in the winter I am usually miserable because of the cold.  This cap is nice and warm, while also being breathable and stretchy.  I have gotten several caps and some are not as breathable, which makes you sweaty, which makes you colder in the winter.  This doesnt have that issue, its really warm and comfy.  I have washed it several times and it still looks brand new.
