I've bought sleeping bags. Sleeping bags that I could afford at the time. I have decided to buy a good one. I've read reviews, write ups, Blogs and am now more confused than ever. Maybe you can help. I want a 15-20f bag. I want it to be light, as close to two pounds as I can keep it, and highly compressable. I also like a semi rectangular bag, or at least a roomy mummy. I am leaning towards a Western Mountaineering, Feathered Friends or a Marmot Plasma. But I am open to your ideas. What do you like?
