Nylofume® Pack Liner Bags

  • Fully waterproof
  • Odor resistant barrier
  • Tougher than compactor bags
  • Ultralight – 0.91 oz (25.9 g)


Nylofume® Pack Liner Bags are fully waterproof to keep your gear dry. They’re made from a special nylon film that's also an odor resistant barrier to help keep your food and smellables under bear radar. Originally made to protect food and medicine during home fumigations, these bags make great backpack liners.

Nylofume bags have been known to last on thru hikes and are found tougher than trash compactor bags which eventually develop pinholes. And they’re lighter at just 0.91 oz (25.9 g).

The material is clear to help you see where things are inside. To seal, simply twist, fold over, and use a bungee strap or rubber band. Or for a loose seal just fold over several times. They measure 20 x 37 in. (50.8 x 94 cm) and fit most lightweight backpacks, but the length can be cut down if necessary. Use one for all your gear or two to separate your sleeping bag/quilt and clothes from your food/smellables and wet gear.



Material: Nylon polymer film, 1 mil thick, clear, unscented

  1. Perfect for Inside an Ursack  star rating

    Posted by MNron on 4th Aug 2019

    We use these as water- and odor-resistant liners inside our Ursacks. We have regular-size Ursacks, but I think these Nylofume bags would fit nicely inside the largest Ursacks, too. We "seal" them by twisting the extra bag material, then folding it back on itself, and holding it in that position with a 6" Holy Grail Bungee--quick & effective. One of ours has been used for 8 days in this manner; it shows lots of wrinkles but no signs of wear or tearing. This 3-pack should last us a long time.

  2. Good size  star rating

    Bigger than the MLD ones. These fit my Arc Haul perfectly.

  3. Exactly as advertised  star rating

    It's a nylofume bag. It'll get the job done

  4. can’t be beat  star rating

    Posted by Timothy S Deatherage on 14th Jun 2019

    I used one of these for the entire 800 miles of the Arizona Trail. It’s less than twice as light as a trash compactor bag and just as strong. Highly recommend!

  5. Excellent  star rating

    Posted by Unknown on 25th May 2019

    Lighter and tougher than contractor bags. Plus, odorproof so can serve as food bag at camp too.

  6. Better than I thought  star rating

    Posted by Jackie O on 12th May 2019

    I bought these on a whim, thinking they couldn't be much better than a compactor bag I usually use. But they are better, so much better. Such a silly thing to make me happier, but what can I say - nice backpacking things that make it easier, lighter - make me happy.

  7. Does the job and lasts forever!  star rating

    Posted by Michelle on 5th Apr 2019

    I bought one of these pack liners over a year ago and it's still going strong. I bought a new one this time to line my day pack. Very durable, weighs next to nothing, keeps everything dry. I don't even use any stuff sacks anymore, just stuff everything loose in the liner bag.

  8. Perfect Size  star rating

    Posted by Art on 18th Mar 2019

    Perfect size for keeping my bag & clothes protected.

  9. SO Glad I Switched  star rating

    Posted by Chris from Florida on 22nd Jan 2019

    I'm glad I made the switch from a compactor bag to a Nylfume Pack Liner. I was so surprised that something this thin and lightweight could be so much better. Glad I found your site and products!

  10. It works and it's light and I haven't torn it  star rating

    Posted by Langly on 30th Dec 2018

    Well it's a bag, it's light, it's transparent, it fits well in a Z-packs Nero, it kept everything dry, it's reasonably priced and it wasn't nearly as noisy as I thought it would be. No holes yet after a few days in cactus and rock country. I'd say it's a winner. Durability to be determined but it looks promising.
