Nylofume® Pack Liner Bags

I love these Nylofume pack liners. They are thin and light, yet durable for an entire thru-hike. I’ve been buying these from Litesmith for a few years now, and I really appreciate how affordable they are and how prompt they ship.

I've purchased and used several of these over the past few years for my food bag to help contain odors. I still prefer a white garbage compactor bag for my pack liner because it's stiffer so things go in and out easier and I load and unload my pack from the top so transparency isn't a factor.

These pack liners worked quite well for my group and I. It absolutely dumped rain on us and these liners kept our stuff dry. Shipping was crazy fast too!

Have used ONE for 3+ years, no rips or tears Lightweight and works great. Simple as that!!

Great bag for an extra layer of water proofing inside your backpack. Have used these in the past with great results - having a dry sleeping bag is huge!

When I started backpacking I began with an Osprey bag liner, as I progressed with upgrading to lighter and lighter gear, I transitioned to the tried and true trash bag as a pack liner. Now I have evolved to using these bags to line my 60L pack. Just finished a 3-day section hike on the AT. These bags are tougher than they look, are definitely reusable, easily handle trail conditions, and when they do wear out they can simply become a regular ole trash bag. Just so you know, the bag is not quite big enough to tie off if a 60L pack is truly jam packed, but almost. And that’s not really an issue for me. I’m really just using these to keep my tent, clothing and sleeping bag dry. Cheap and it works. What more do you need?

I’ve tried nylofume bags sold by other vendors, and they’ve proven to be significantly less strong and louder than the Litesmith ones. As usual, Litesmith has found the absolute best product.

Great that it is an odor barrier...for those rare nights when I keep my food in the tent I store it in my 2 pack liner bags....

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.

Lightweight and essential piece of gear.

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

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.

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.

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

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.

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

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.

Fits my Zpacks Arc Haul perfectly. Plenty durable and much lighter than other pack liner options.

These pack liners are the best on the market. Lightweight, yet sturdy, durable enough for my 12-day trip. Got caught in a torrential downpour, and everything in my pack stayed dry thanks to this liner. The extra few ounces are totally worth the peace of mind, and simply a great product and a great value.

Works perfectly, lasts long, super light. Good price!

Just got these liners and I took one out backpacking in some sand dunes. They fit well in my REI Flash 55. There was a storm and everything inside the bag stayed dry. It was lightweight and durable. This was only a one night trip, so I'm not sure how they hold up over time, but I would buy them from litesmith again because of the great service, accuracy, ease of purchase and communication from the company, and fair prices.

Bought this as a replacement for my heavy plastic pack liner - this is much better- light, fits pack well and appears very durable The service from Litesmith was excellent - no hassle, products promptly dispatched , good communication. I would not hesitate to buy from Litesmith again - highly recommended

.9 Oz and super cheap. Very durable so far.

Ultra light, durable and inexpensive. These nylofume bags are amazing

This is super light weight and very durable. I use this to stuff my quilts in (hammock camper) press down, twist the excess bag and fold it under itself and then place into the bottom of my pack. For the cost this is a no brainer, no need for a fancy DCF rolltop or draw string baggie at 10-15x the cost.

As durable as a trash compactor bag but much lighter and clear. At first I didn't trust they'd last, but they do.

These pack liners are a game changer for me. They are light, durable, thin, and, most importantly, very water resistant. They are also clear, which is a big benefit for me as it makes it easier to see the contents of my pack. I use one of these for my 48L pack and another one for my small day pack, which I cut into a smaller size to better fit the small pack.

Really quality stuff, and shipped fast!

Lives up to the reputation.

Conforme à la description du produit.

Very happy with this product. It is light weight and does not tear easily.

Mine clocks in at 1.1 oz. Fits my 60L mariposa perfectly. The crinkle noise is LOUD. Thankfully it's only noisy when packing and unpacking, and not walking (at least for me).

Extremely light weight and durable compared to a trash bag. My new go to pack liner!

I've used compactor bags for many years as pack liners. They are very tough and inexpensive. Recently I read about the Nylofume bags and how they were even tougher (though that is yet to be seen when compactor bags last for years!) and lighter (they are about an ounce lighter), so I thought I'd give them a try. I've only used them on one trip so far, but they worked great for compressing and protecting my down gear. Since they have odor resistant properties, I'll probably give them a try to line my bear bag as well. If there is one downside, it's that they make a crinkly sound like a chip bag. However, I didn't notice it once they were in my pack. The only reason they get four stars instead of five is that their longevity isn't proven yet.

I use these bags to protect my equipment in my backpack as well as in my bear canister

These do the job and seem very strong. They don’t have any stretch like garbage bags.

I bought these liners for backpacking thinking I would give them a try , I was surprised how much lighter and truly stronger than the compactor bags I was using . Lol never thought I’d write a review for a damn bag lol

Bought a 3 pack last year and hiked 17 days on the Appalachian trail in GA and NC. Replaced the first bag after 10 days when I tore a hole in it with a tent pole. Still have one bag left. They weigh almost nothing (1oz/29g) but are very durable. I carried a second one just in case. They make a crinkly sound like a potato chip bag but it's not as noticeable after a couple days use. Much better than a trash compactor liner for keeping gear dry. Bought another 3 pack for this year.

Un accessoire indispensable pour les randonneurs ultra léger!

I like these bags. Their durability is longer than other bags.

have used the liner on one trip so far and it worked as described

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

Best pack liner for all sizes. Also Durable .

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!!

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

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

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.

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

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

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!

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

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.

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.

Perfect size for keeping my bag & clothes protected.

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!

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.

Right size for my bag (exos 48). Didn't have to endure wet conditions yet, but having a clear bag is an improvement over trash bags. I was expecting a bit of noise, as the material is crinkly - but that wasn't a problem.

I got these to help prevent raids by the infamous ninja squirrels of Havasu Falls and I can say that results are positive! There was no evidence of attack or even attempted attacks despite seeing multiple invaders around our campsite during our stay. I don't know how many victims there were among our fellow campers but good campsite hygiene certainly made us a less inviting target. The bags themselves are surprisingly durable for their thickness and I plan on reusing them for future trips which definitely increases the return on investment.

Great pack liner with excellent durability. Very light and doesn't tear easily, it just stretches after applying some force.

these bags look and feel tough, perfect for a liner or bag , get a pack of 3

This bag is perfect, way lighter than trash compactor bag. The only compactor bag I have is in another country so I can't compare. This is how I found litesmith, I didn't want to purchase a whole box of compactor bags so I was researching alternatives and found a better option along the way. Pros: No waste (unless you own a compactor) Stronger Lighter No stretch (allows you to compact air out of your quilt as you pack Con: Just a little noisy (when your stuffing it its a little loud. its quiet after loaded up)

This is the lightest pack liner I have found, and other than the loud material (which I was expecting) it is perfect. Material noise is similar to a sun chip bag, and is only an issue if you are packing up while others sleep.

This is fresh on the heels of my switch to a polycro ground cloth for my tent and a switch from Tyvek. Over time I'm getting more interested in getting lighter, and shockingly the groundcloth shaved six Oz from my load, and the bag liner looks like it's going to hold up swimmingly. Taking another oz off the pack will either help go lighter or facilitate another desired item to get added in. Either way, a win!

Trash compactor bags are pretty heavy for what a pack liner is supposed to be, but these bags are light weight and very durable. I'm able to fit most of my important gear (sleeping bag, etc.) that I want to keep dry in one comfortable. With a second one I can keep all my gear protected.

I really like these liner bags, they are stronger and lighter than trash compactor bags. Also transparent so easy to find things inside.
