There are two things I like about this hat: how light the material is and that it is made from cotton. I'm allergic to acrylic and have found that pretty much every hat has acrylic in it. To avoid this, I would always not wear a hat and use a hood instead. This worked fine when I drove everywhere, however after living in windy Boston without a car for 5 years, I decided it was finally time to get a cotton hat. In addition to the itchy rash I get from most hats, my head is always too hot. This hat solves both those problems and is comfortable to wear.
