The Canadian Forces in Afghanistan wear camouflaged Tilley hats.
The brim on either side can be folded and clipped up like the famous ANZAC hats.
Because of its flexibility the brim at the front can just be scrunched up for vertical shots. It will flop back down on its own.
Really hot day? Soak the Tilley in cold water and apply to hot head. Ahhhhh.
Tilley floats. So hard to starboard and go back to retrieve it. No need for a diver.
It can be tossed in the washing machine and even ironed if you are finicky.
No. I am only a customer. I get no commission. Not even a discount.
