Great hat for me but still hot!
I was looking for a "baseball" cap with a longer bill to wear while hiking. This one looks good and washes well and is comfortable, but it's still hot (on our warm days) and I stilll sweat a lot. Haven't found one yet that really isn't hot! I bought another one since I liked it.
