A beanie that actually keeps your head cool and sweat free? When I first read that I thought to myself that it was a preposterous statement, another attempt at a "summer beanie" that while may be thinner than regular beanies, still make your head hot...but not this one. Not only is it thick like a regular beanie, it does exactly as advertised. I live in the Caribbean, where the sun shines down and it is hot, and this Coolmax yarn is not only keeping my head and my dreads sweat free, its keeping me ultra cool even when I'm not in the shade. Couldnt be happier with this product, will definitely be ordering more, and hope they come out with additional colors soon. Thanks King & Fifth, you've made a believer out of me.
