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 Originally made to protect food and medicine during home fumigations, these bags make great backpack liners.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

    1. Cottage Service!  star rating

      Posted by Chad Grissom on 19th Mar 2020

      There isn’t much else left to say, this is indeed THE pack liner. This liner fits beautifully inside my HMG 2400 Junction and can comfortably accommodate ALL my gear without presenting the fear of water escaping into the inside. You hear talk about these bags being “louder” than the competition when packing/unpacking, I was leery going into my first purchase due to this. I can proudly say, this bag is NOT loud and more importantly bomber! Enough about the bag, I’m sure at this point you have done enough research to realize this is the bag of the majority. What I would like to speak of is LiteSmith as a company! The members of this team are at the top of their game in terms of customer service, off trail “trail angels” if you will. I called (LATE) due to realizing I was out of liners and was only a few days away from escaping to the trail, I was advised to submit the order and ensured they would be to me without delaying my start day. Again, leery...go figure, I open my mailbox to realize that my liners had made it from CA —> TN in 2 DAYS! This alone is why LiteSmith has a customer for life. Customer service goes a long way, thanks guys!!

    2. THE Pack Liner  star rating

      Strong, extra large/long... I can even use it to wrap my pack in it for a plane ride.

    3. Surprisingly durable  star rating

      Posted by Monday on 25th Jan 2020

      As a long time user of compactor bags I was hesitant to try the nylofume liners. To my surprise they are incredibly durable, light, and fit perfectly in my pack. Litesmith’s listed weight was spot on and shipping was fast. Great product.

      Very lite weight seems very tough material,just been in 2 night trip but worked very well

    5. 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.

    6. Good size  star rating

      Posted by Unknown on 29th Jul 2019

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

    7. Exactly as advertised  star rating

      Posted by Unknown on 23rd Jul 2019

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

    8. 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!

    9. 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.

    10. 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.
