I agree with both of the above.
We have the greeny bucket / floppy hats, as was said, comftorble, VERY practical, and when your on the fire ground, or returning from it, it's not like your trying to impress people ne way
(Well, there are probably some out there, but thats not the point
)
I say use the "Baseball Hat" if doing anything corporate or image related (only if your not out doors:P) and get more of the bucket hats!
