I actually have a couple of them, my new camaro hat from the chevrolet dealership is a flex fit. I personally like the flex fit, wether my hair is a bit long or cut short the hat fit perfect every time. Plus you don't have that patch of hair trying to work its way through the hole of an adjustable with these. It may depend on how you wear your hat though. I wear my baseball caps like a baseball player, all the way down on my head, I notice some gentleman older than me sometimes wear there hat up high on there head, it may fit differently for them. I like the wool style professional fitted baseball caps the best, but the flex fit is my second choice of hat. I have never had a flex fit crawl off my head, in fact some have a thin band of like a rubber spray that prevents the hat from moving even more, just depends on the manufacturer I guess.
