I plan on using a dri ducks jacket for my outer layer in wet conditions. No pack cover. Just a pack liner and dry sacks. However, I have a short Neoair and want to use my pack under my feet while sleeping.
Problem: Pack gets wet, don't want it under my down bag.
Any advice that won't result in me adding weight? I've thought about going with a poncho of sorts to cover the pack too while hiking, but I don't want to add any ounces. Also not really interested in a pack cover. Of course I could always buy a cuben fiber cover or poncho, but I really don't want to spend over $200 on this issue. Grazi.
