This is the only hat of this type I have found that does not constantly work it's way up and off; resulting in a weird sticking up point.
It also has more of a rounded crown with little angularity.

I wear a 7 1/2 hat.  I saw one review complaining about a tight fit.  I get a loose/just tight enough fit; so, I don't get that.

It does not seem scratchy to me, but scratchy wool does not bother me.
