    Would this also work on sweaty balls, if you were to place it on your groin?

    Doesn't look very well made, more like something a garden shed inventor would make as a prototype.

    Surely a garden shed inventor would invent garden sheds, not hats?

    i thought they'd attached fans to baseball hats for warm-weather sports enthusiasts years ago. Or is the innovation here that they've made a "green" alternative?

What do you think?
