I’m heading on my first Elk hunting trip in Colorado this October ( 2nd Rifle). I’ve got a teton xxl cot and a canvas cutter dominator. I’m trying to decide whether to buy a nice sleeping bag or to get some nice wool type blankets. I’ve done plenty of summer, spring & fall camping just never anything where the temps dropped below 40. I have a Davis wall tent with a stove on the way. I can’t do mummy type sleeping bags but the large rectangular one I have now gives me plenty of room to move it’s just rated at 50 though. I’m a large guy 6’4” 290lbs currently and need some room to move around when I sleep. What is everyone using?
