Here's a test I'd love to see..

Take a standard extra large size ziploc freezer bag bought at the grocery store.

Take any number of bags sold as "odor proof"

put food in them with the outside of the bag in a clean pristine state.

Test them all against animals. see if there is any significant difference.


If there is, then please repeat the test again, using the odor proof bag for the same test, after giving them to backpackers to store their food in for a week on the trail. compare that to a new ziploc bag (because lord knows I'm gonna use a new one. it's cheap!)


Sorry, the only thing I smell in any of the odor proof bag discussions is snake oil. I have more food smell in my beard after I eat on the trail, in my breath in the morning after waking up, in my underwear after my on-trail flatulence with a high fibre diet, than sits on the outside of a clean sealed ziploc.

(and the ziploc will not stop bears, critters or anything else. hang properly or use a canister or ursack)

I use an ursack. I don't use the silly op liner, I use ziplocs.
