I have a cap which I bought several years ago that I LOVE. Seems like I bought it from either TE or Athleta but neither carries it anymore - ? The tag says Illuminite, and I found it on their website:

It stays on in the wind - I've worn it in 30 mph + wind, it's well vented, and it has some reflective insets on the sides (although I don't think the reflectors work well at all - ). And it comes clean in the wash.
