I've always been partial to a mummy bag, but I'm trying to ditch my amazon budget bag (rated for like 45) and get a nice, lighter in weight, 20* tq/bag. Since I'm on my oh-so familiar budget I'm looking to spend very little...I've seen the occasional budget bag like the Kelty Cosmic 20* go for like $60 or less before, which would be awesome since I know it's an awesome bag! Anyone got anything sitting around that they'd be willing to let go for cheap? Trying to get into the woods sooner to bear the cold Dimensions of myself: 6'1" 170lbs. I'm typically a warm-ish sleeper unless I didn't eat much. I'd prefer to get a lightish weight bag below 3-3.5lbs...my current bag is like 5lbs and doesn't compress very well and that sucks lol
