I am taking my golite poncho tarp and do not have a pack cover. No money, either. I would make one but my last peice of anything waterproof is too small. I thought about tyvek - which I have two rolls of - but am not too willing to invest the time to make something that I might hate. That leaves the poncho tarp. I could hike in it, but the wet arms bother me when it is cold. I was trying to figure a way to attach it to pack without bungee cords if possible. I plan to be careful of snags. The wind could be an issue with slippery silnylon.
Any suggestions on how to use this as a stable pack cover?
