What gauge vinyl laminated nylon is used for haul bags?

I’m looking to go diy haul bag, the choices go 10,12,14,16,18,20,30,40,60,80 gauge. My instinct is to go with 60 or 80 but I’m not trying to haul extra weight for fun. Does anyone have any insight on this? 

I really would reccomend you instead source a PU laminate instead of vinyl this performes far better and isn't as horribly toxic for the enviroment.

Source?

Source for PU laminate fabric, source about it having better abrasion resistance or source for Vinyl being awful for the environment?

More importantly, What machine will you be making this on?

At what gauge does this become an issue between home vs commercial grade? I have access to every tool and every product ever made.

Does anyone know what gauge PVC fabric or PU is used for your recommendation, there’s still a lot of variety out there for either material.

If I remember correctly, landfill liners are PU but good luck getting your hands on it. 

While Seb's suggestion is right, you're not going to find it easily in low enough quantities for a single bag.

land fill liners are HDPE, it's non toxic and very cheap.

It's very difficult to source, I have been able to find a source here and there over the years but never followed through with the project i'm also not in the US so any source i could offer wouldn't be very useful. You could always skip the laminate all together and instead just make it out of UHMWPE you would have to waterproof it your self but all part of the fun.

Dont have access to textiles textbooks atm for PU properties but i'm sure a quick google you will find them.

Extremtextil in Germany has TPU-coated fabric:

And also a lighter version that's only coated on one side:

I also considered making my own haul bag, but welding the fabric seemed like a PITA  so I bought a Metolius haul bag instead.

Check with Fish.  He Knows.

From a recent instagram post from bigwalldeuce:

@wallaceclimbing the best material for haulbags is the urethane (not pvc) 28 oz/yard or 32 oz/yd. currently only Runout Customs is using the best stuff. Metolius used to use it but went with a cheaper material a few years back, presumably when they took production offshore. BD bags were also originally the best double coated urethane, but apparently they also have cut costs on their bags. Seaman, Cooley or Uretek are the manufacturers of the good stuff, originally developed to be fuel containers for offsite military ops.

Very helpful, thank you. 

I came across some fabric I think would make good lightweight haul bags.  Serge Ferrari  Satin  502. Basically a 16 oz reinforced pvc  with a Polyvinylidene Fluoride varnish (Related to teflon, only lighter) on the outside. Lighter and very slippery. My sewists don't like using it for some projects as it slips under the presser foot.

Would be a lot less work to drag over the rock.

I have a few yards of it I could sell if needed. Or you might check out the local awning shops.
