I wear a 60cm will this hat fit me am having a hard time finding a hat to fit me perfectly?

Has velcro adjustment strap in the back that allows you to adjust fit to your head. Works very well and looks good.

How about listing the F=n size. The only piece of information that is needed.

It says "one size", whatever that means. I'm returning it because it is huge!

"Dark purple"? The picture doesn't look dark purple to me. Is it darker in person?

sorry I did not order purple I ordered Tan/sand. a little heavy but it fits my head had to adjust the back as I guess I have a small skull now without any hair due to chemo. but nice hat

What is the material of the hat? Is it 100% cotton or part polyester?

100% cotton. I've had this hat for quite a while now & wear it often. It has held up nicely & has not lost its' shape. Not flimsy like other hats I've purchased on here.
