I do have a straw "sun helmet", and it's very shady and cool, since the sweat can evaporate through it. But I really only wear that when I'm doing serious sweaty work in full sun. It's a pretty odd hat and I won't wear it out in public unless I'm looking for laughs. My USAF boonie hat gets used too.

For some reason, my body shape doesn't work with brimmed hats. Every time I've worn a full brimmed hat, I feel like I'm all out of proportion. Some guys just look right in them, and some guys don't. Maybe it's the shape of my face, or the size of my shoulders, but something's weird!

But despite all that, I'm seriously thinking about getting one of those Tilley hats that are lightweight and ventilated. Seems like the perfect hot-weather hat, and would probably go OK with the rest of what I'm wearing. None of it matches anyway, LOL.
