What might be missed is that the Tilley hats have a pocket in them made to hold small amounts of money or paper work etc. I have a small zip lock bag in mine that can hold important numbers or money no problem. There is also a piece of closed cell foam in the top of the hat to keep it floating should you drop it over board. I have put a double thick piece of foam in mine to give me more protection from the sun or knocks to the head. This also helps it float better and keep its shape when wet. The Tilley’s are good gear and I would not want to be with out mine.
