Last year I purchased an "Eddie Bauer Oiled Canvas Fedora" hat while in Oregon (at an Eddie Bauer factory outlet for about $25; Amazon ASIN B005MRBCBW, presently about $25 plus $8 shipping) for use in the sun and rain there as well as in the tropics where we were moving to.  The hat is well made and I like it flexibility and durability -- it can be flattened or rolled for travel and storage.  I store it flat under the front seat of the care and have essentially have taken it everywhere.  The hat has worked well at shedding heavy rain and provides some sun protection.

More recently I purchased  this hat ("Large Khaki Classic Cotton Adjustable Hat" by Sloggers (Amazon ASIN: B001G9GABC, presently $17.70 w/free shipping)) while overseas in the tropics for about $25.  Although the Eddie Bauer hat is a good hat, I prefer the Slogger.  The reasons for this preference is that the Slogger has a wider brim (for rain and sun protection), it's lighter weight, and it has a more comfortable fit -- and it has the same "take everywhere" flexibility and durability of the Eddie Bauer hat.

Although I prefer the Slogger, I have given both hats a 5-star rating because they both are good hats.
