A Real Test for Odor-Proof Bags

NyloBarrier Odor Proof Bag

I use LiteTrail NyloBarrier odor-proof bags to store my backpacking smellies in when I'm out on the trail. I use the PCT bear bag hanging technique most of the time to make sure that bears can't get to my goodies and so far it's been completely successful. How do I know if my odor-proof bags are really working?

I've used the same odor-proof bags to store my food inside of bear canisters in California on several occasions with apparent success - no bears tried to get the canisters open or run off with them, but I don't know with any level of certainty whether that was because of the amazing capability of the odor-proof bags or if there were simply no bears wandering around on those occasions.

I've tried just about all of the other well known odor-proof bags on the market and have been disappointed in them, usually by how they function as basic bags (zip closure failures, or bursting open at seams) rather than their odor stopping abilities. They were expensive and didn't stand up to more than a few uses.

LiteTrail NyloBarrier bags are extremely durable, two times stronger and 50% thinner than 2mm polyethylene bags. They're also light weight at 0.4oz (11.5g) and 70% lighter than an OPSAK 12.5 x 20. At just $4 for a pack of three they are an amazingly low-cost odor-proof solution.

  • Weight: 0.40 oz (11.5 g)
  • Size: 12 5/8 wide, 24" tall (8" diameter as cylinder)
  • Chemical, oil, grease and thermal resistant
  • FDA food grade plastic that is safe for food
  • ASTM F1927 odor barrier tested.

Real-Life Odor Test
I think I've finally found an empirical test of the NyloBarrier bag's ability to block odors over an extended period of time - poop storage! Yes, the good old WAG bag came to the rescue yet again by providing me with an opportunity (it was not planned) to put one of my beloved NyloBarrier bags to the ultimate odor-proofing test.

Any odor-proof bag that can successfully block the stink of several used WAG bags, stored inside for multiple days in the scorching California heat wins my official seal of approval - for what that's worth. I used my spare bag (yes I carried a spare despite the excessive weight) to store my WAG bags inside during my second trip to Mt. Whitney this summer. Without going into details that you do not want to know about (trust me) lets just say that after more than four days of use there wasn't even the slightest smell of poop coming out of this bag.

Don't believe me eh? Well, imagine the surprise of the park Ranger when I pull this bag out of my backpack at the Inyo Forest Ranger station as I'm returning the rental bear canister at the end of our trip and ask if there is a place here where I can deposit it. "What's in it?" the Ranger asks and is amazed, because of the lack of smell, when I tell him it's my complete matching set of WAG bags from the trip we just completed.

So trust me when I say that the NyloBarrier odor-proof bags really work. I won't be using any other bag for storing my food and smellies in while backpacking from this point forward. I just hope I'll never have to conduct this type of test ever again!
