I have a smaller than average head but this still fits well do to the knit. I bet it comfortably fits larger heads as well.

Satisfied with the fit too.  Our grandson has a big head too so we were concerned about the fit.  Very satisfied.

Nice hat, nice fabric, fits well. Just the thing for persons with heads.

Little bit small. However the person I bought this for does have a head that's a little on the large side. Fit my 12 yr old son perfectly though.

I am an adult with a normal sized head (I think), and it fit just fine.  The quality is great for the price.

Better suited for a smaller head.  Needs a bit of attention fresh out of the pouch, but nice and thick.  Good for the price

The small medium size is a little big for my head. I hope that washing it will size it smaller.

Love the color & style. I have a very small head, it is slightly large on me. It would probaly fit an average size person well.

I bought two- one for a friend and one for myself. We were going to redecorate them for an event. I have a smaller than average head, and she has an average size head, and it was a bit tight in her. It fit perfectly on me.

Fit is good on my smaller than average adult female face. works well with my Giro Recruit size small and Marker M2 XS helmets. Will give a further review after I wear them on the slopes of Breckenridge in a couple of weeks.

Lightweight, but warm. Was a little on the small side for me. I wear 7 7/8 pro-fit hats. Good for most average sized heads.

Purchased as a gift for a guy who has a L-XL hat size.  He wears it during the day and as a sleeping cap.  He shaves his head and needs a cap to keep warm.  He liked the masculine color too.  It's a medium weight cap.

This is my second purchase of this hat. I wore my first one for work outside in AZ everyday and it was looking a little shabby after about 3 yrs. My first was a medium, head measures 22.5 inch and it was a little small. the large fits better. The mesh helps keep me cool, it folds up and cleans easily.

Helmet fits good, feels good. Doesn't make your head look huge.

This was a gift for my son. I measured his head and went by the sizing chart and it fits perfectly.
