    Waterproofing a backpack

    Anyone here waterproof their backpack? I got caught in a little sprinkle this morning, wasn't bad enough to deploy the raincover or poncho, but got me thinking about waterproofing my Osprey. I have some Kiwi Camp Dry silicone-based waterproofer that I use on my boots, I was thinking I could also use it on my pack. If you waterproof, what do you use?

    I tried a couple of different things over the years but I've found a simpler and cheaper (yet more reliable) system: I just line my pack with a really thick trash bag and pack everything in that. Anything that goes in the outside pockets is in small dry bags.

    That way, I don't care even if the pack is completely submerged, I'm still good.

    Anything that needs waterproofing in my pack goes into a ziplock and at the beginning of the rainy season I use a waterproof spray on my packs.

    What about Nikwax? Suppose to be the best. I sprayed one of my shells with it but have not tested it yet.

    I am a full hearted believer in the use of some type do waterproof liner bag. One time my wife and I did a train trip through a couple of cities on the east coast. The goal of the trip was to get out an explore these cities on a shoestring budget so we traveled very light with only a small daypack. Mine was a "waterproof" military style rucksack and hers was a Walmart bought Jansport style knockoff. Since her's was obviously not waterproof at all I purchased a box of those super big ziplock bags so she could put he stuff in it inside of it. One day in Philadelphia we had to walk quite a distance in a torrential rain storm. That night when we got back to the hotel and unpacked our bags my stuff was ALL soaked and her stuff was completely dry. I dried my stuff as well as I could overnight and then took one of the garbage bags from the small garbage can in the bathroom of our hotel room and reloaded my bag in the morning. That next day it was raining again and we had to walk pretty far to get to the train station. Even though I only had a super thin 1mil hotel garbage bage as a liner that next night my stuff stayed dry. Sometimes the cheap and easy solution is the best solution!

    To my experience sooner or later there will be water in the pack, no matter how you waterproof it, whet the manufacturer promised, what raincover you use (with the exeption of those roll-closure messenger pacs).
    I also dislike packs with waterproof bottom, as you will carry around several pounds of water after a downpour without drainage.

    I too use different sizes of plastic-bags to keep my stuff dry plus a commercial dry-bag for the sleepingbag when volume is an issue. This system also makes the pack float, which can be a big plus.

    Contractor bag as a liner. Everything goes in the bag. I still use a lot of gallon and quart ziplock bags as well and every ziplock has a spare in it.

    I was thinking about the Kiwi silicone spray myself, for the cheaper packs that is. My NorthFace packs have sealed zippers, while the others dont. That would be a likely point for water entry, but I think the OP is referring to just a quick light rain, or else they would have taken the time to deploy a rain cover.
    I've resprayed nylon tarps with the Kiwai spray and it works great at repelling water.
