I did just get one of these. I don't really plan to run in it, got it more for less strenuous outdoor activities, but I can give it a try on a run tomorrow and give you my impressions. It's only in the 70s here right now though, so I won't be able to give you any feedback on hot weather performance at the moment. It does have an elastic drawstring adjustment, which sounds like instant headache to me, but it might help it stay on better.

The Athleta hat I have isn't in their catalog any more. I got it as swag from a retreat several years ago.
