I have a trip coming up in Feb with the scouts. I want a down UQ, but that will have to wait for better days. I have a 30 deg mummy bag that I was going to attach loops and use it as an UQ. I don't think that it will be warm enough and was thinking about also using a poncho liner. Does anyone have a thought on this idea. I know not the lightest idea, but I don't have to pack it far. Which way would you hang it, hammock-mummy-PL or hammock-PL-mummy? Any idea on a temp rating? Any help would be greatly apperciated!!
