Cotton takes a long time to dry and isn't that tough, double Ventile maybe I guess and the old British Cadet smocks. If you're on a longer hike and camping cotton stays sodden and clammy unless you treat with say Nikwax wash-in Cotton Proof, but then you lose some breathability. Polycotton's better for faster drying, G1000 and the like, but polymide is best I'd say. Paramo's Fuera classic is so so good, and the older Rohan smocks and jackets knocking around on ebay. These are all tougher than Pertex as well, though for tear-restistance polycotton's best. Cheers.
