I have for sale two Marmot Couloir right hand zip, regular sized, 0F, downsleeping bags for sale. Condition is used, but well maintained and CLEAN. These bags are toasty; technically rated at 0F, however marmot sandbags their ratings. They are probably actually -10F in other brands.Asking $350/sleeping bag. I live in Ketchum, ID and can possibly deliver to CO or UT this fall/winter.
