After spending too much time running around trying to bag my pack on cold nights, I have found a simple setup that attaches to the outside of my ALICE pack. It is just forty feet of paracord with a loop at each end attached to a heavy duty carbiner. So far, in the yard, it has been pretty easy to lob the carbiner over a limb and then clip it on my pack. Hopefully, it will work in the bush as well. No grizzlies or super savvy bears where I hang out, so this might be all I need.
