Kakadu Australia Cape York Hat - UPF 50+, Packable (For Men and Women)

Bought it to get sun pro for high country and ocean.
Since previous buyers felt it was sized too small, I bought the 2xl for my second-largest size head. It fits well although a quarter size smaller is about right - but see below.

The brim is broad, and although it flips up going into the wind, will keep you sheltered as well as a cowboy hat.
polyester canvas with water repellent = mut bueno: won't get as heavy as nonrepellent hats, and it appears to be the toughest stuff around for epic bushwhacking.
Australian style hats are made with a better brim shape than cowboy-style hats, or than my guatemalan straw hat. Less sun in the eye.

You can wear a large backpack with this hat, as the flexible brim bends without notice. This is a BIG positive, as other brimmed hats cause you to push your head forward, making posture bad and backpack to become painful fast.

Ugly baseball caps don't protect. The outback hat here is the best thing going, unless you like caps with skirts, which can be hot. those and hoods prevent you from hearing. I like the sound of bears, birds, and the rest better than solipsistic hoods.
That slightly too-large choice can accommodate a fleece toque underneath, too.

Haven't washed mine yet, but they do get nice and grubby looking with greasy hands, mud, dust. Totally fine, as brand new is too urban.
