Caveat: I ordered too large. I can't wear it around before sending it back, and so cannot predict how it would handle crushes and crimps. It appears *from casual inspection*, to be too rigid to fare well. I could be wrong. This hat is beautifully made and detailed. The headband is a soft cotton-seeming mesh. The sides are lined with a silken material, and the crown has a clear plastic lining, apparently to deflect ponded rainwater caught in the molded groove on top of the crown. It would be stylish insulation in cool to cold weather, probably overkill in warm to hot--though that would add authentic "Indiana Jones" sweat stains. The hat overall is as rigid and unyielding as if stamped out. I *believe* I wouldn't be able to drive in it because it would either bounce off of, or be crumpled against, the anti-whiplash headrest. Again, it looks really good, so I would hate damaging it.
