I have been using the Outdoor Research Radar Pocket Cap for a few months. I originally checked it out at REI because of the style and lightweight material. Upon closer inspection the bill has a seam down the middle which allows the hat to be folded and then wrapped in itself. Awesome design and material. UPF 30, super small when wrapped-up, very light, and nice fit. It is a fitted hat so trying it on is necessary. Best hat I’ve owned in awhile.
