Trying to shave packing up times in mornings. Thinking a grocery store plastic bag would be lighter and easier so you could simply fold shelter..Solong 6 in my case..versus carefully folding and rolling so it will fit in the tight awkward length stuff sack. The wide bag would also stack better in the pack as you could simply tie shut and place I top of compactor bag then place food bag on top. All the bag does is keep inside of pack clean. Would also make it easier to take tent out during a long break to dry out....
PS
I hate plastic grocery bags and wish they were banned...
