This is the second copy of this hat I have purchased.  It protects my face and ears all day without giving me a headache or allowing heat to build up.  The first hat lasted over 10 years.  Then, the sweatband no longer absorbed sweat.  I had cleaned it many times.  But, in the end, sunscreen just clogged the sweatband too much.  For those with receding hair lines of baldness, be aware that the sun comes through the vent and will burn you.  So, put sunscreen up there, too.  To prolong the life of the hat, I have learned to leave the area on my forehead where the sweatband is without sunscreen.
