For years I was using a Tilley hat as a rain hat.  Well, I guess it finally ran out of rain-proofing.  I found myself feeling drips of rain creeping down my forehead under my Tilley.

I bought this hat and it is perfect.  In a downpour my head stays bone dry. I have to remember to bow my head before coming in the house because it holds a pool of water when rain is heavy.  The hat is comfortable and the rim keeps glare out of my eyes.  I strongly recommend this affordable (compared to Tilley) hat.
