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 Originally made to protect food and medicine during home fumigations, these bags make great backpack liners.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

    Size: 20 x 37 in. (50.8 x 94 cm) flat bag, ungusseted


       To the Top: 3168 cu in. (51.9 L), based on 8 x 12 x 33 in. (20.3 x 30.5 x 83.8 cm) to the top, flat bag with ungusseted bottom

    1. Love the new quieter material!  star rating

      Posted by Unknown on 6th Jul 2023

      Finally had to order a new liner after years of use and love the new quieter material! Seems just as durable as the old formulation, and is of course just as waterproof! Full day of hiking in a downpour and all of my gear was still dry. If I could give 10 stars I would!

      [Litesmith] The product has not changed.

    2. Sturdy and Simple  star rating

      Lightweight and essential piece of gear.

    3. Keepin' it Dry!  star rating

      Lightweight packliner. Just what I need to keep my stuff dry.

    4. No Leaks  star rating

      Posted by Unknown on 22nd Nov 2022

      Been using these backpack liners for years. I do not use stuff sacks. All of my downy goodness and clothes go in the backpack before I twist the liner off. Food and rain gear go next. I have never had a bag leak on me and I have 100 percent confidence in these liners. These are a must have for me.

      Used it inside my pack while hiking and slid my pack into it to store it in the vestibule at night.

    6. Lasts >1000 miles  star rating

      Posted by Zen on 28th Feb 2022

      In roughly 2,200 miles, I’ve gone through two of these liners. The first separated at the bottom, and the second got a cut in it. I love that they’re 100% waterproof, durable, and lightweight. I was worried about the crinkle, but never noticed any sound when it was in my pack. A little loud when actually packing it, but that’s a minute long ordeal, in a 24 hour day.
      I don’t think you could get a better pack liner for any price. I will continue to use these for as long as I backpack.

    7. Quality Product  star rating

      Posted by Joe Schellenbach on 14th Feb 2022

      Fits my 55L pack with room to spare and lighter than a compactor bag.

    8. Not bad at all.  star rating

      Posted by Unknown on 23rd Jan 2022

      Not sure if there's anything that can compares in terms of finding that sweet spot between durability, weight, and water resistence. These things work excellent for my needs, and the price is fair for what you're getting. I get a lot of uses out of one liner. Always a pleasure buying from Litesmith.

    9. Awesome addition to back packing  star rating

      Posted by cutlass on 21st Jan 2022

      These bags are great and can save so much space in your pack.

    10. Big enough to line a pack and keep bears safe.  star rating

      Posted by SlowBro on 25th Sep 2021

      Great product. As a pack liner, plenty big enough for a 60L pack and durable enough for a 400 mile trek. Kept everything dry in the pack. Used a second one to line my food sack, we were in grizzly country. Glad to say no bears visited our campsites during the month. So I'd say odor-proof, too. I don't think you will find a lighter alternative.
