It is Extremely Comical,at the Very Least!,& Noisy as All Get out!I have AMK Heatsheets & Bivvy bags,They are fabulous,but noisy also!I carry/use a Space Blanket-Ripstop Nylon,They are Much larger than the cheap blankies,But Give back a Whole lot more,should the need arise,That in Unison with a Military Poncho,or even a Cheaper Poncho,Would do someone Very Well!Remember,Make use of Available Ground Trash,Whenever Possible,It doesn't have to be a Debris Hut,It could be a Big pile of Leaves/Branches! Insulation is The key!Make sure you know what Poison oak/Ivy/Sumac,& Nettles look like,Before gathering debris! The Cheapy Blankets WILL work,But you will be Miserable!
