I really liked this Columbia straw hat.  It looks good and being packable is a major plus.  But unfortunately, for me the hat was uncomfortable.  The only sizing choices are S/M and L/XL. I had the opportunity to try on a L/XL and found it to be too large.  So I ordered a S/M from Amazon hoping it would also be on the bigger end of the range.  Unfortunately my head size falls into the gap between the two ranges.  If it fits your head, I think that you will like this hat.
