The Allen bags can't be used like a gunny sack where you grab the top of the bag and all the meat/quarter falls to the bottom. The bags are not strong enough and will also stretch, allowing flies access. So, tie one separate loop of line to the quarter. Place the quarter in the Allen bag or roll the bag over the quarter. Now use another piece of line to close the top of bag. I use a constrictor knot to securely close the bag to the boney top of the quarter or directly to the first loop tied to the quarter. The Allen bag now is loosely draped over the quarter, not stretched by the quarter and the top of the bag closed. When you pick up the bagged quarter do so by grabbing the quarter AND the bag....or by the loop tied to the quarter. Hang the bagged quarter by the loop tied to the quarter. Again the Allen bag supports no weight and acts only as a barrier to insect and dirt while allowing the meat to form a dry "skin." If you can't figure this out then use the TAG or Caribou bags.
