I got this hat in the reddish color with the navy underside and am hoping that Oiselle will make more colors with a dark underside. (A white/light colored brim on a sun hat doesn't make any sense... It's a great way to reflect more light onto your face. Maybe okay, and sometimes even desirable in Seattle, but not where I live where the sun is intense and I want maximum protection.) It's really light weight and pretty breathable for a nylon item, and the brim is the perfect width for full face coverage without sacrificing too much visibility. It doesn't have a lot of structure due to the thin fabric, and I was skeptical about it holding up in wind, but so far the brim hasn't budged in 15-20 mph wind. Time will tell if it flips up with bigger gusts but I'm very happy with it so far. It is a little on the big side for me (though I like that as it helps with ventilation), and I have a medium sized head, so if you have a small head you'd be swimming in it unless you have really thick hair. Oh, and the bird print on the underside makes me happy every time I look up. 🙂 I wouldn't change anything about this hat and would definitely buy more colors in the future.
