I bought this hat to take with me to Hawaii. Packed really well although I did not fold it up in the suitcase. I did fold it on occasion when I was out and about and it popped right back into shape. I wore this in the sun and I wore it in the rain. It was pretty comfortable to wear, I really hate hats because they make my head sweat, this wasn't too bad.  Glad it is vented. I have a fairly small head and this fit fine. Happy with my purchase.
