I need an outer bag to protect my expensive sil-nylon bag from rips when I go off-trail. I do not want to trash a $25 bag everytime I go out. I have been using an old REI packcloth stuffsack and it is now full of tears and holes. I was looking for cheap material to make a cheap light outer bag. A plastic bag would just get ripped up. Anyway, the post was essentially about how flimsy and worthless the material is on Coleman ponchos.
