Good hat, it's soft, comfy, wicks moisture away well, and doesn't seem to form salt crystals as much as other hats. Since it's wool, it shouldn't get a nasty funk to it as often during lengthy summer tours.
well-made hat, just bear in mind that it is made of very thin jersey fabric. i'm guessing about a 170 weight. i was expecting something much more substantial, but i can't really fault the hat for that. if you are looking for something very thin, this hat should be high on your list.
