What size canvas/bedroll do you need to be able to wrap it around you while also having a wool blanket wrapped around you? Asking because I want to know whether pic related would actually work. It is oilskin lined with 80% wool and 20% Cashmere. Could be good on those cold nights. Not sure if it is big enough to actually wrap yourself and a blanket with though.
