I carry a newspaper delivery bag in my pack along with 1 gallon ziplocs and quarter bags. I immediately quarter and debone all meat, get it into the ziplocs and start the haul out. I put the first load into my newspaper bag and remaining ziplocs left unzipped into an elk quarter bag. This allows for quicker cooling while the first load goes out. 9 times out of ten I can make two trips and get it all. I use this same method for hauling deer as an entire mule deer quartered and all trimmings will fit in the bag. If the terrain is too steep I will bone the deer out though. I use the bag with front and rear pouches which your head slips through the middle of. When you are all done stick it in a five gallon bucket with bleach water, put a rock on it and rinse it out a day later.
