I also have a boonie hat. It is some off brand I purchased several years ago. It is my favorite hat, though. It has some amount of Thinsulate and was advertised to be Goretex. I have worn it walking (not working) in wet snow and the outer wet through but it did the job for my head. I like a hat rather than having to always wear a hood.
If it is rainy but warmer and not windy, I can just rest the hat on top of my head rather than pull it on. The shape of the hat gives me a bill while the sides flop down over my ears (wind gusts push them flat against the windward ear), and the back has a nice round brim.
I mostly walk in cooler weather and typically the hat is for light walking or resting (Long stops to use a camera). When I am working in cooler weather, I use a wool beanie cap. It is easy to put on or remove and tuck away while walking.
I also have a Columbia Bora Bora mentioned by John. This is a nice warm weather sun hat for me.
As far as hats blown off, both of my brimmed hats have bungee cord in the crown. I tuck the chin strap up inside the hat and tighten the bungee. The bungee runs below the.. skull bump at the back of my head and at the top of my neck muscles. Maybe I have a pronounced skull bump… My hats have staid on in wind that had the brims shaped like unhappy umbrellas. I did fit the chin strap loosely while in a boat (seemed prudent) at about 35-40 mph. Not in the bow, but not behind a windscreen and the hat staid on. Much stronger wind and I think the hat would go. Prehensile eyebrows help, too.
