This is the greatest hat, I had owned a Columbia version and would come home from walking dogs and look like I was wearing a wet dish cloth, hair beneath soaking wet too. Not so with this hat!  The brim design is generous enough to keep rain drops off your face and glasses (if wearing them for early morning dog walks).  The chin strap tightens well and keeps the hat on your head in brisk winds.  If you are looking for a rain hat, of good design and construction, this is it!
