I am bored silly by baseball caps, and prefer sun protection to going hatless. My options in headgear are restricted because I live in a region of the US that features almost endless wind. My fedora-style hats blow off, and even the Australian style hats with chin straps are a botheration and torment. Hence, the flat caps best exemplified by Kangol. which stay on my head. The ventilation is very, very good, and the quality of manufacture beyond complaint. In brief, a good product and a happy customer.
