I made these Gaiters for my husband. The bottoms of jeans were always getting soaked from the snow and rain. I found the pattern online from a store in Corvalis, Oregon. They were easy to make, but it still took about two weeks....LOL But if I would have stayed on them it probably would have only taken a day or two to complete.
It is a waterproof shell with a canvas lining which I plan on spraying some waterproofing on them later today.
