This hat from Dorfman Pacific is simply great. The material is very nice and soft. The only con I would cite is that, being a special edition from Indiana Jones, it has a small plaque on one side which says "Indiana Jones", well, since the hat is mine and no Mr. Jones's then I removed it.

The material is sturdy and it really is both fresh and waterproof. I am a structural Engineer and I have to do various kinds of inspection work, this hat has proven invaluable protecting my head from the sun and the rain. This hat is easy cleanable an you can stow it away with your other backpack items and it will recover its shape easily.  I have not treated it with much care, took it to an earthquake disaster zone and it underwent some Indiana Jones kind of treatment and it keeps going.  Bottom line is the hat is durable, practical and you could take it either to the field or use it, if you dare, like Mr. Jones, with your suit.
