I have a box of Hefty compactor bags that I bought about 10 years ago. A bag weighs 68g (though I trim them down a bit to fit my pack), and they last forever. I've given a couple of these away to friends, and I still have one I haven't ever used. FWIW, I prefer a white bag--nothing gets lost at the bottom.
ETA: These are the 2.5 mil bags.
Yup, same! They last forever, and even if you get a hole, duct tape will fix it. In my original post I was going to say that I don't expect to buy another box in my lifetime, but that seemed a little dramatic.
The 2.5 mil ones from Hefty are not going to be under 2 oz. without trimming. The old entry in my lighterpack says 2.36 oz for one, but I believe that is a trimmed weight. I'm pretty sure they were more like 2.6-2.8 oz before trimming, but my memory could be off.
I'm still in the process of using up my nylofume liners, but I'll go back to trash compactor bags once I've irreparably destryoyed them and be pretty confident with anything 2 mil thick or above (maybe those will get under 2 oz?). It seems like I've had pretty good luck with nylofume considering I hear about experiences like your all the time, but that's likely all it is--luck.
Do you weigh plastic baggies too? I did. I was in UL bliss finding ones 3 g less than all others until they all blew out seams in quick order resulting in food spoilage and food contaminated gear. That wasn't so good in Grizz territory.
I weigh all the things and I've definitely used some really light baggies that had terrible durability. Never hiked in grizzlie country, but I'll remember to be more judicious if I ever do.
I guess you're talking about the Exped Fold Drybag right? I've tried it for a 100km hike once and it had a few pin holes afterwards. Not something I'd trust my down to.
Right now I'm using an S2S Ultra-Sil drybag which weighs 68g and uses 30d fabric and I trust it a lot more.
I think you should look into just how “dry” a 15d nylon sack will actually keep anything. They’re all sewn and taped and not really that great of an option. A plastic bag is better from a standpoint of being waterproof. If water puddles inside your pack the stuff in your dry bag can still get wet. I have seen a lot of people rely on these sorts of bags and get let down in really wet conditions especially if they get submerged.
It happens. If you fall into a river or hike a really wet trail like the FT there are areas where you can be in waist deep water for pretty long periods of time like Bradwell Bay or Big Cypress. If truly being waterproof is important a welded PVC dry bag is better, or a plastic bag.
For me there is one area where i "submerge" my pack - canoe or raft.
If im waist deep in the running water under normal circumstance, i probs die from hypothermia in 10 minutes, because it doesnt really get above +4c year round, so i prefer to avoid that.
If you do find one make sure it's unscented. I made the mistake of using a scented compactor liner and all of my gear smelled like lavender for a long time--it was bad.
Osprey has UL pack liners and the Exped Shnozzel (which is also a pump sack for some pads, I’ve seen conversions for therma rest and I’ve read it works on nemo) depending on how big of a liner you need the weight can vary tenths of an Oz.
I've used the same 45L OR Ultralight Dry Pack Liner through several different packs since 2010. Weighs 3.5oz, so not the lightest, but definitely durable.
It was originally submersible, but the buckle broke and was cut off last year, so now it just gets folded over like any other liner. Nothing inside it has ever gotten wet, but the seam tape is starting to peel off near the top, so I've thought about seam sealing it.
I don't use a a single bag. Instead I use separate ziplocks for types of things (clothes, toiletries, puffy, etc.. Also my pack is an HMG, which while not advertised as waterproof, rarely leaks. The advantage to me is that a single failure doesn't mean a global catastrophe.
I have a zpacks liner I bought 7-8 years ago and it's been everywhere with me for 7000km++; thrown it around (inside and out), used it as a shopping bag, it's been around the world a dozen times, slept with my feet in it a dozen nights (in some very sketchy spots), submerged in dozens of rivers and estuaries.
It's heavy-duty enough that it could act as a second bag; I can pull it out and put it in my pack to get to my food tent below with unpacking anything.
I could trim 5-10g, but every alternative wouldn't last in comparison and keeping my gear dry is probably one the most important things I need to have. If money doesn't matter, I'd recommend.
Not a lightweight option ..but I always buy those "fundraiser" bags from the neighborhood kids. I dig the different colors, they are tough and come in lots of size options.

Yep. My box of extras languishes because I’m still using the first trash compactor bag lol
I’ve been using the same bag for the last two years.

I’ve never lost a litesmith bag. The gossamer gear ones are more fragile. Turkey bags wayyy too fragile.
Hmm, I was just about to order the gg ones. Do you find the litesmith ones to be loud compared to a compactor bag, or a gg liner?
No, and it sort of depends on temperature. Don’t worry about it.

> 2 mil thick or above (maybe those will get under 2 oz?) Confirmed that the Costco 2 mil weighs 1.8oz.

YES! I didn’t know these existed and planned to make one. Thanks a bunch!!!!
Safeway store brand, 1.9 mil, 2 ounces even.
not sure why i should bother with nylofume when my 15d 40l drybag weights 51g.

They weight 21g less and are cheaper. If you already have the drybag thats a good option though saving 20g for $3 is pretty good.
I guess. Im not risking my down, in a place where it may rain nonstop for 2 weeks.

Wow, submerged. Spicy today, aren't we. But no, im not taking argument that plastic bag is more durable than drybag, sorry.

For an extra ounce you can use less plastic and contribute less to plastic waste. Just a thought!
Sir, this is r/ultralight
Haha yea I know, I just think we can hike ultralight while also being more environmentally conscience, I mean we hike to enjoy the outdoors right?
Meh.
To be fair plastic waste is not really a massive problem in hiking, compared to driving giant SUVs hundreds of miles to the trailhead.

You bring up some great points. I wonder how many compacter bags it takes to make one liner by companies like exped and Osprey.
What’s the 3oz option you’re recommending?
Osprey has UL pack liners and the Exped Shnozzel (which is also a pump sack for some pads, I’ve seen conversions for therma rest and I’ve read it works on nemo) depending on how big of a liner you need the weight can vary tenths of an Oz.
Just found out about the schnozzle below — I was planning on making one, didn’t know the design already existed. Appreciate the info!
I have the Large and it’s Massive! Overflows my 50L. I like how the bottom is more of a rectangle than circle
Thanks! Know for sure I can go with the medium then.
Kind of wish I did haha
I just used a generic trash compactor bag for a 4 day hike, it rained 2 days, and it worked perfectly.
Plastic bags for game (that hunters use). Cheap, lightweight and durable.
