Proof Storage Bags-12ｘ20 Inch, Reusable Double-Tracked Zip Closure Barrier Storage Bags Lock in Keep Contents Fresh and Waterproof, Large Bear Bag fit Camping, Hiking and Water Sports （2 Pack）

These work SOOO GOOD! They work so good that the inside of the bag doesn't even retain any odor after you've used it!

These bags are of a nice and thick plastic that I believe will prove to be quite durable. I put about 2 days food in one for a backpacking trip (12x20) and there was space to spare. I couldn't smell the food once it was zipped into the bag so I do trust that they are scent free. I wasn't concerned about bears on my trip but rodents. I kept this bag with the food in it in my tent and never had any issues with critters. Makes for a nice bag just to hold and organize your food and does not weigh very much

Used these to hold trash to pack out - put them in a rat sack after - kept "dirty" trash in a separate place to easily pack out

I used this bag to house my wife's jar of kimchee in the fridge. It worked and family order was restored. True story.

What I care about on bags like these is that they have strong & reliable seal. These do so far based on some use during traveling and camping. As far as I can tell, they also do a good job of keeping oders from escaping, but I don't have the sensitivity of the bears I'm trying to dissuade from being interested when I'm hiking.

I have not loaded these bags up with food yet, but they are impressive. Much larger than I expected. And sturdy. So far I think they are worth the high price. But I don’t know yet if they really block odor. I would not be comfortable using these instead of a bear canister, but as far as see-through convenience of holding all your food together, they seem great. I think they would also be good for separating clean clothes from dirty clothes in a pack.

I use on every hike for garbage wrappers and food storage.

These are heavy duty and will be useful for any Storage that does not require odor control. Odor proof should be that. I tested them and they were no more than partially effective, the contents were not as odorous but you can still smell what it is

Good bags ! Work great camping keeping animals away! Zip work greet and still reusable!

One of them ripped the first time I opened it. A rip off you might say.

I think these are just standard oversized ziplock bags, and a little pricey - no need to buy them again.

Expensive snake oil… just came back from a back country portage trip! Watched a bear climb a tree and sniff to my bag with everything in these bags! Didn’t get it because I know how to hang a a food bag without getting it… not these bags! Never will buys again! Recommended not wasting your money!

I put less than a half oz of cannabis in the bag, sealed it up tight as instructed, and came back to my car two hours later with it REAKING of weed. This wasn’t even primo stuff. You can smell it right through the bag really clearly. This bag does not even work half as well as the Smelly Proof bags, and those are pretty bad to begin with. Will be demanding a refund for these useless bags. If you have stuff in there that a bear wants, you can guarantee he will find it and find a way to eat it. Fully convinced this bag is a sham. Says it’s Good for “long term storage of biohazard waste,” too! HA! You will kill people with this type of advertising. It is extremely irresponsible. Fix your product.
