I was amazed at how functional the hat is. I bought it because my dermatologist is always burning off pre-cancers on my head and body. It has a wide enough brim to keep my ears, nose, neck and face from the sun but what I found out about the hat is that it keeps my head cool. Much cooler than a straw hat I wore for working outdoors. I now know why Indiana Jones wore this hat in the desert's heat. The wool felt and leather band do an excellent job of absorbing the sweat and in return, cooling the top of my head by water evaporation. The high crown keeps the heat from building up and I found that I stay cooler much longer by wearing this hat. Something I never thought of when buying it for protection against the sun from my oh-so-white skin.
