I don't know if you would be interested, but my company is currently developing an anti-odor food bag that will block almost all smells. I've tested it on raccoons, bears, and mountain lions. Within the last week, my preliminary bear testing showed good results, and is now ready for further testing. The bears were unable to locate the food hidden within the bag.
Currently, I'm searching for people who would like to test these bags out, and provide critical feedback. They can be used inconjunction with your bear canisters, or by themselves. Let me know if you are interested? I can arrange for free samples in exchange for helping me out.
