If you can help me find our ideal sleeping bag, I would be so, so grateful! I‘m looking for something that is under 5 lbs carrying weight, the lighter the better, for cool/cold weather, has a flannel, brushed polyester or other soft/plush inner lining, with a water repellent exterior cover, and compressible insulation. Extra points if it is rectangular in shape! Any ideas??? All brands models considered. Thank you, Thank you, Thank you :) Jaspen
