This hat has excellent reviews, which is why I bought it in the first place. This has been with me through thick and thin, cold and hot, rain and wind.
So, it's a hat and it's awesome, what more is there to say? I think that it is very comfortable. The bill is a great size to keep the sun from blinding you or, in my case, to keep vehicle headlights from messing up your night vision.
This hat is also very low maintenance. I just chuck it in the wash after every few runs and it's good as new. I've had this hat now for probably 4 years and I still don't think it's ready to give up anytime soon despite the hell I have put it through.
In comparison, I have a Patagonia hat that is terrible. The strap on the back goes loose mid run, and it's heavy and uncomfortable. This Headsweats hat has absolutely no complaints from me.
