yep thats them where all the rage in CadetsWhen i was much younger, i remember a surplus shop in Halifax, West Yorkshire, called Ben Aaron's (near the North Bridge). It used to sell surplus German Army sleeping bag's that had sleeve's and a zip across the thighs. This enabled you to unzip and free your legs; the bottom of the bag folded up and clipped onto the rear of the sleeping bag at the base of the spine. At least that's how i remember it, or did i dream it? Anyone else familiar with these? I think they were half lined with moleskin, half quilted.
