I saw this in a zoo gift shop.  I really liked it, but it was way overpriced, about $10 over retail.  I don't mind paying a little more at gift shops, to help support such places, but not that much. When I got home I bought this for much less on Amazon.  This is an excellent hat for protecting yourself from the sun.  It has a nice wide brim, that, so far, hasn't gotten "floppy."  It is well ventilated, which is  something I need in the Arizona desert. It's very lightweight.  I have a large head and most "one size fits all" hats are too tight for me, but this is perfect. For older children or small heads it has an adjustable, elastic cord to make it fit snugger.  There is a sweat band build into it, which is a plus.  Similar hats I've had did not have this. It seems very well constructed and I think it will last a long time. I've owned several similar hats over the years and this has been my favorite.

The hat itself is 100% nylon except for the trim.  It has to be hand washed in cold water, but I expected that.

Overall I'm very please and can recommend this item.  I liked it so much I bought a second one for my 12 year old daughter.
