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 Originally made to protect food and medicine during home fumigations, these bags make great backpack liners.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

      I haven’t tried this yet but it’s light and fits my sleeping pad and bag perfectly and will definitely keep everything dry

      I originally bought just one and used it for a few overnights, nothing crazy and it worked out fine. Then i did a 14 day section hike of the AT and it somehow got two, 1/2 inch punctures in the mid bag. I'm still trying to figure out how that happened b/c all the reviews I've seen and usage reports from other hikers say these bags are practically indestructible. The only thing that i think it maybe could have been from is a rub mark on the dry bag latch that i use to keep my quilt and clothing in as thats the only thing in my pack that even has edges. If not that, maybe something in my front meshy pocket but i dont keep sharp objects in there either. I really have no idea.

      Regardless, i just bought 3 more. At the end of the day, they cost 2.50 so i'm not too concerned. More just mystified how my first one developed holes.

      I bought a three pack and the first bag was still keeping things dry after 10 days and nights on the Appalachian Trail and it rained every day! I had a 50 liter pack and the bag held all my clothes and sleeping gear. I like that they are lightweight and inexpensive. One reviewer complained about the crinkly noise (like a potato chip bag) which is true but the more I used the bag the less crinkly it sounded. On the last day of hiking I tore a hole in it with the backpack zipper. I put a piece of duct tape over the hole and used that same bag for six more days of AT hiking a few weeks later (only rained every other day on that trip). They work great!

      This is a great pack lining material. I like it better than a trash bag because it doesnt puncture unless you really want to poke a hole in it..which obviously you dont. Reusable. Does the job.

      Heard of nylofume bags on r/Ultralight. Shipped out super quick from when I ordered. I was afraid I wouldn't get them before my overnight trip, but they arrived in time. Bag fit very well inside my Osprey Talon 44. It could for sure accommodate larger bags, though I don't have one to try so I can't say how large you can go. I think 55-60L would be fine. Material seems very tough, yet light. Fortunately, it didn't rain on me so I can't say how waterproof it is.

      June 2, 2020. Great for storage, long-lasting, and strong. The bags I received were the same as those given to me when the house was tented years ago and I still have and use some of those. They are stamped as nylofume on the bag. These bags are large, measure about 20 x 39 (overall 40x78). These work well for camping to keep things free of bugs and water pending on the closure.

      Way lighter than contractor and compactor bags. Seems to be a very strong bag so far. Will definitely purchase again

      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!!
