When the hat arrived, the first thing I noticed was that it was a bit too large.  According to the size chart, it was my size, and the next smaller size would probably be too small.  So I was stuck with something that wasn't perfect, but I could probably get used to it falling down to my ears.  It definitely would not do well if it is packed into a suitcase, which is what I had hoped to do for my upcoming trip.  I'm also not sure how well it would stand up in wet weather.  It's made of a pretty heavy material, so I agree with one of the other reviewers that it might get pretty uncomfortable during the summer.  All in all, the only good thing about it is the price.  It's dirt cheap compared to other hats of similar types, but if you want a really good hat, I'd suggest looking elsewhere.
