Many years ago I had a Second World War Officers Bedroll which I used as a weather resistant cover for my sleeping bag. It wasn’t as waterproof as a bivi bag but it kept the bag in good shape under rough conditions and was comfortable to use. As I’ve been using a hammock mostly for the last decade it’s been stowed away and was getting pretty tatty anyway so with the purchase of my new Baker tent which will see a return to ground sleeping for me, I decided to make a new cover along the same lines. I started with a 2m length of 14oz canvas, 72" wide and folded in two, sewn into a bucket for the feet, edged with cotton webbing and with ties of the same down the side to close it up. The long ties you see for binding the roll, also serve to secure a pillow when sleeping. For packing, you stuff the bedding down into the foot bucket and then roll the canvas around the whole thing. Here it has the two bag system I used in the Arctic but I'll probably just use a couple of blankets on a cotton stuffed palliasse atop a stretcher when I'm in the tent.
