Tilley is the way to go....they really are vastly superior to any boonie I have ever worn or seen, comfortable, protective and long long lasting so cheap in the long run.

Do not discount them....you would not be disappointed. My favorite is the T4. I do not like the unshaped standard T3 or shorter brimmed T5. They offer a hemp mocha T4 that will be my next Tilley. I also do not like the light nylon versions (T6) but my wife prefers them over the canvas models for sunny days.

They can take any degree of crushing, folding, wet or sun that you dish out. There are ebay dealers who offer decent prices and selection. Make sure you order it large enough...follow their measuring advice...a tight Tilley is the wrong size.

I do not recommend oiled cotton as it is relatively hot and a Tilley once wet sheds rain just fine without cooking your head in the sun like an oiled hat does mine.

In my view a Boonie is not even a hat.
