Well I can't see from his forum picture the top of his head so... you jest but you never know!! ;-)
No offence mate but a lot of hat wearers get this not just fedora wearers.
Seriously though, I know nothing about fedoras and those felt type hats but a guy I know through work who is Texan born and bred told me that modern "ten gallon cowboy hats" have a major problem that film and tv westerns never really show. That is the rain really buggers them up. That is why you get plastic cowboy hat covers. You do see that with US cops like the sheriffs who wear them in films. They often have the plastic bag over the top in rain. Anyway I do wonder if that happens with other felt hats or hats made out of similar materials. That is why I somehow suspect the flexibly fedoras might not be good in less than clement weather. It could of course be the weight of the wider cowboy hat brim of course.
Now tilleys and the like have a slightly stiffened brim or at least the cotton is stiff and only gets stiffer in rain from what I heard. I still can't bring myself to get one though. I think I look a prat in one. Other people look ok but for some reason I don't think I can carry off the look. I do want one though but won't. I'm stuck with a baseball cap and plenty of sun tan lotion on the ears, face and neck instead. Did have a cap with the flap but it was pretty short. Still it was bought very cheaply on that hottest year back in about 2004 or so when in Wales and it was 36C!!
