I'm one of those people who doesn't do heat well, and I have to wear a hat anyway. I really love this!  It stays cool just as advertised, and keeping my head cool in this summer heat (and I imagine maybe later in the year when I'm just kayaking and perspiring a bit) is so awesome! Thank you for a great deal on Amazon Prime Day! I love the color, too, and it's light and comfortable to wear.  I bought their Multi-Cool 12-in-1 neck wrap/head wrap thing and it is also a lifesaver for me.
