Sorry, but you won't get me back in a bag. I don't care how cold it is. My quilts have served me down to 20F and will go with me every time, and I don't have a problem. You have to use them to learn to use them effectively. I've had trouble with gapping, but I don't any more. I also toss and turn, particularly when sleeping on the ground.

For ground sleeping I would gladly take a 4 season quilt from Jacks R Better, one of the larger ones will be more suitable, and with full omni tape down the quilt sides and a drawstring on each end, it will serve in any configuration you want it in. I won't be doing any arctic expeditions, but I'll be out in winter with one in the Sierras in a heartbeat.
