I'm only giving this watch cap four stars because, to me, it wears "tight" and seems "scratchy". That said, I recognize it is scratchy because it is 100% wool. However, because it's, "one-size-fits-all, it's cut smaller than what I would consider an average size head thus it feels tight on me after wearing it for awhile.
I would recommend it if you only want to wear it for a short period of time, but go with a polyester of you want more long-term comfort.
