Well, I usually just deal with it, but this last trip it finally got to me: the smell of coffee permeating through everything in my backpack.

So, is there a good way to prevent food odors? I usually pack everything in ziplocks but food odors still emenate (on this last trip I triple bagged my coffee to no avail). In the past I have had on occasion the taste of one food penetrate into another - coffee flavored mac-n-cheese...blah. To top all this off, it's not cool sitting in bear territory when you reek of food odors that has clung to your clothes that were packed next to a smelly bear canister earlier in the day.
