Structured is more rigid, right? I think my favorite hats have been unstructured due to my weirdly shaped head. But then again, most of the structured ones I've tried were not made for large noggins.
Edit: The trucker style with the mesh makes it comfortable to wear in the heat. Are those...
Bodean, any chance that your hat supplier has some larger sizes for us full-figured big head guys? Am I right @patride71 @bottombracket ?
