For next summer's (mid May) possible Damsascus->North trip, I'm thinking about not taking my sleeping bag at the start and using, rather, a silk liner and a bivy bag, or perhaps overbag. I am a warm sleeper and I'd have my insulated pullover, warm hat,
etc for colder nights. Comments? My current (and only) sleeping bag is a Marmot Arroyo 30 degree bag. It weighs, according to my scale 2 lbs 9 oz. Being cheap, I don't want to spend several hundred dollars to get a WM Megalite and save, I suppose close to a pound. Nor do I have the skills to make my own quilt. I am, also, unfortunately, too big for the WM Highlite. The Kelty Lightyear weighs significantly more than they list and the Marmot Hydrogen seems to weigh more as well. Is there a reasonably priced 40 degree bag out there that truly comes in around 24 oz or less?
