Waterproofing a leather hat?
Most of the time, it's great, but it does leak through the crown if I'm out in heavy rain for more than, say, 30-45 minutes.
This isn't normally a huge problem, since I'm not often out in heavy rain that long that often, but it is a problem on a wet camp, when I'm outdoors all day.
Unfortunately, I can't polish it, as the finish is matt, borderline suede.
Any ideas, folks?
