Wiggys is making garments out of a fabric he calls Ducks Back because it sheds water so well. Anyone have real world experience with it?
He sent me a small fabric sample and it does indeed repel water rather dramatically. I can’t get water to go through with a couple minutes of effort and rubbing.
I can suck air through it with some effort so I would rate it as breathable but not very.
