We usually just carry the light packs and when someone gets one down one starts in on the cutting (I usually carry the game bags with me so I have them to start right away). The other guy goes back for the frame pack and I usually have a couple quarters ready for them when they get back. I have also just tied them to my pack and hauled them out. I have a blackhawk pack that I put all the loose stuff inside in a game bag and a back quarter tied to the outside (Lots of weight) got all bloody but it washes off. You want the meat to cool and breathing helps. If it is cold enough the plastic would work but it wouldn't be my first choice.
