I know that it is possible to use a lighter weight bag along with insulated clothing and/or a vapor barrier to effectively lower the rating of the bag.
I am thinking of using a Western Mountaineering Summerlite bag with a light fleece layer and a Mont-bell Thermawrap layer (top and bottom) if needed. Doug Prosser says that he also uses his rain layer for sleepwear.
Since all of these layers are also needed if the weather is cold or rainy before bedtime how do you manage to keep them uncontaminated by food? If anyone can share their "system" I would appreciate it.
