Why? stick a small kitchen garbage bag inside... that's water proof - not water resistant. Easier to keep it clean. UL etc. etc. etc.
Yep, best way.Quote:

Most backpacks I see, especially the internal frames, are essentially nothing more than fancy duffle bags with shoulder straps and a few pockets attached. They sell "dry bags" that are just that without the shoulder straps. What, is this really rocket science?

7200 cu.in. even tipi would approve.
pretty cheap too
a pack cover
The only things that will get wet will be the ones at the bottom of the pack. Use one dry bag for the sleeping bag.
Waterproofing a pack will make it difficult to clean in a washing machine.
Cover it with some polythene bag which is very easy and also effective.
+4 on the trash compactor bag. Easy, cheap, waterproof, UL and easy to replace in the next town should you get a tear. Make sure anything in an outside pocket goes into a ziploc bag. Also, if it's raining and you're hiking, consider a poncho that fits over you and your pack. Double protection.
visit YouTube and sniff around for waterproofing tarps. people do it with silicone (the stuff you buy in the big tubes at Home Depot or Lowes) squirted into a bucket and mixed with paint thinner (or some other solvent). you just mix it until the silicone dissolves into the liquid, dip in whatever you want to waterproof, and then hang it out to dry in a well ventilated area.
also great for doing laundry away from water sources,Quote:

Uh, people, carefully read, and perhaps reread, what the OP asked. He asked how to WP his backpack not specifically what goes inside the backpack.
I think you are asking how to keep your pack dry. That is, keeping your pack from absorbing water. Don't know what fabric your pack is made from but spraying or washing just the pack with Granger's Waterproofer would be the way I would go. It's a versatile product which can be used on many different types of fabrics. It works well. Might have to ocassionally reapply it though. Then use the internal liner idea with or without the added safety of WP stuff bags to keep specific gear like your sleeping bag dry. Could also go with the a WP pack cover after waterproofing with the Grangers for added protection. Find the combination that works for you under your typical hiking situations. Hope that answers your question.Quote:

Making a pack waterproof is a different matter, so KK gave a excellent alternative. But I will add this - I have been using a garbage bag on the inside in case the bladder leaks. Its in it's own sleeve and my clothes will stay dry even if the bladder leaks. So I think these are good answers.Quote:

I also have all my gear in waterproof Cuben stuffsacks, plus my sleeping bag encased in a trash bag. That setup has worked just fine for me, but I wouldn't expect the DWR treatment to last more than a few weeks of backpacking.Quote:

I keep saying this and I'll say it again - I rely on the storage volume ON THE OUTSIDE of all my backpacks ie: rear shovel pocket, side mesh pockets, hibelt pockets, etc to stotre items I don't want to get TOTALLY DRENCHED and I do not want to store those items all in individual WP/WR stuff sacks or baggies so I'll sometimes, like when I know I'm going to be hiking w/ a high risk of heavy or long duration rain, w/ a liner, pack cover and additionally DWR/WP my pack!
Except: Wet backpacks get heavy when wet. Why carry the extra weight? It rains a lot on the AT. Use an ultralight pack cover, plus a garbage bag inside. Belt and suspenders. Keep your stuff dry.Quote:

I'm an Old Phart. Educate me:
Why do I need a trash compactor bag when I have a gross or 3 of Glad Trash bags under the kitchen sink? A pair of Glad bags doubled in my Terraplane is no heavier than the compactor bags.
Ziploc bags: My first line of liquid defense. What's wrong with that?
Keeping the Terraplane exterior dry: Poncho. Done.
The Jensen pack is a bit trickier with the two vertical columns. The principle is the same: Plastic bags inside. Poncho outside.
So, why do I need trash compactor bags?

I'm glad you've had good luck with regular garbage bags; I have not. Even doubled, they don't last me a single week without multiple breeches that would let water in. I find that compactor bags last about a month. Nuthin wrong with ziplocks or ponchos, though I finally graduated to higher tech rain gear (maybe, what... 35 years ago or so?). I still have my trusty Terraplane though! Hanging proudly on my wall. Right next to my 6 pound ash handle ice axe, all never to be used again by my own Old Phart bones.Quote:

I usually use a 1.05 oz Nylofume bag as a liner.
I test my liner every day for holding air . When I find a small leak, I put a piece of ducttape over it.
A wet pack, is not going to let a lot of water in a small leak on a liner. If the pack fills with water and the leak is at the bottom, then sure. Ordinarily, small leaks in a liner are inconsequential.
Most folks dont - I have in off season a down jacket and a down mummy in a Sea to Summit dry bag. I think I mentioned I had a Bladder bag failure once where the drinking water ended up on the inside of the bag all over the equipment - it was a O ring that fell out of the cap that cause the problem.Quote:

I use a pack cover, compactor bag, and individual bags. My experience is that my issues are always setting up and breaking down in he rain. Don't think I've ever had complete sucess when it rains for 3 days straight. The big issue always seems to be my feet. They just can't go in the backpack.
Don't use a Cordura pack, don't use a pack with open cell foam padding...Quote:

I prefer Ziplock bags really, they are waterproof and help you organize your gear.
