i too am interested in this to find out how to do a DIY version...i know the material is "canyon cloth" which is proprietary to mountain hardware, nylon doesn't take pleats well, but having cotton anywhere in the blend is an outdoor no-no...so what synthetic material will take a pleat well? poly? i know 100% wool is ideal but not in hot weather...maybe a wool/nylon suit material blend? what about using cordura? that won't take pleats well either, but it will wear like iron...
hmmmmm....
