I am interested in buying a Marmot Flathead, size regular sleeping bag. I prefer if it came with the cotton storage sack. I have several stuff sacks so if it doesn't come with a stuff sack that is fine with me. Also, I had posted this earlier, I am interested in a 8 X 10 flat tarp that is made of silnylon and one with tabs rather than grommets (like the one from Etowah outfitters). Thanks!
