Pack liners work well for a couple nights out, maybe three or four. But I find that they are prone to getting holes, even the tough compactor bags.
I switched to a compression/dry bag for my sleeping cloths. And, another dry bag for my food and other things that need to stay fairly dry. The rest can pretty much get wet and I don't really care. Pads don't soak water, stove, cookwear doesn't matter, tarp doesn't matter, and so on. If I get soakd, I won't melt. Mostly I use my rain gear, but like so muc of that stuff it is only good for a couple hours of rain. After that, I am mostly wet anyway.
In the ADK's, getting wet is mostly normal. on any given day, I expect about a 50/50 chance of rain. In high summer, maybe not. Then spring and fall can shower, sometimes with thunder and lightening, most days. After a week or two, a liner is pretty destroyed. Also, when I take a canoe in, there is a chance I can flip it. I HATE to have my sleeping gear and food all water soaked.
