I have an idea to sew canvas to one side of a wool blanket. The idea being that the side against your body is wool and the side exposed to the outside is the canvas. You get the breathability, windproof factor, and the water resistance of canvas. Also this would be used more when you have little to no shelter or are in an open hammock. As of now its just a thought. It might already be a thing but I haven't seen anything similar before. If you have any ideas, concerns, or anything to add id love to hear it! Thank you!
