The hat looks well made, no visible defects, and fit me perfectly.  I usually were a hat size of 7-1/8 (men).  I purchased this for an up coming trip, and will be using it daily for 3 weeks.  If there are any issues, I'll update this review.

Just finished a 3 week trip where I wore this hat daily.  Functioned and held up well.  However I realized that any hat I've ever purchased has the size/ID tag sewn at the rear of the inside hat band.  I would look for the tag as a quick reference for proper positioning on my head.  In doing this I found the chin strap was not in the correct location.  The tag is actually sewn to the left side of the hat. Not a big problem, just a bit aggravating for me.
