A sleeping bag is only as warm as the user, and is largely determined by the loft. Down, traditionally, has offered the best warmth to weight ratio of any insulation. It's also very resiliant in that it maintains it's loft over many years, unlike synthetic. The Marmot CWM is one of the warmest sleeping bags available and you should be dying of heat at 32degrees, sweating being the biggest complaint. If your freezing in it, I would go see a doctor. It might be your hypothalamus acting up...(kidding of course). Unless there is something wrong with the bag, meaning all of the insulation at the feet has drifted elsewhere in the bag, you shouldn't be experiencing cold problems. Down drift can occur if the baffle material has been damaged or ripped. I would contact Marmot and possibly send the bag back to them for inspection...What(if any)sleeping pad are you using? The down on the bottom of the bag is compressed by your body weight and looses its insulating capability, therefore you need an insulating sleeping pad to keep you off the cold ground!
