I've given up trying to find a suitable hat for sea kayaking. They are either good for the sun or for the rain but not both.
So I figure I'll make one. Goretex (or clone) for a waterproof, breathable top, enough flotation so it won't sink and a hat band that allows air flow underneath.
My problem is figuring out how to make a brim that will be stiff enough to handle serious wind without flopping around. It also has to be something that can be repeatedly soaked (and frequently laundered) without disintegrating. It should also be something I'm likely to find locally without having to order from the other side of the planet.
The brim will go all round the hat, not just a bill like a baseball cap. Think of a cross between a Tilley and a sou'wester.
Any ideas? TIA
