Maybe you guys can help me out. So lately I've been working on a design for a survival sling. By that I mean an easy to make but well made/made to last sling. This question is largely hypothetical as there is about a hundred things I would make in such a situation before a sling but play along if you want. I went with a split pouch because it's easier to make quickly from just fiber. I have some other things I'm going to add to it and I will possible detail them in another thread but the main question I have is what would you guys use in this situation to protect the pouch from wear? Assuming you had no access to leather right off.

I was actually putting together a post about a similar topic but I never actually got around to posting it.

I make a habit of always keeping a bit of paracord on hand, so I'm not sure if this is what you're going for, but I think it's pretty close.

Anyway, I replaced a lot of the laces on my shoes with paracord but for times when I wear sandals or if my shoe are too nice to have paracord laces, I have a loop of gutted paracord that I wear as a bracelet.  It's about 7' long and it can be folded in half and just 3 knots turn it into a quick sling!

Leather pouch with paracord release and retention cords. This setup would be very durable yet if one part broke it would be very easy to replace without braiding. It's also light and small enough to be carried in a pocket comfortably.

All good answers. Technically I guess you could use a back pocket of your jeans. I had not considered that.

Assuming, hypothetically, that you were making it out of just materials you could gather from the wild? Is there a suitable substitute for leather? You definitely could make a solid pouch. That would work. My only thing is in my experience in make fiber from the quickest sources of natural cordage, it can really wear down due to abrasion quite quickly.  So solid pouch or split, I am still running into that problem of abrasion resistance.

I would want something that was very comfortable for me to use plus I'd want it to be versatile.  For longevity either paracord or polypropylene would be fine.  They are almost impossible to wear out.  As far as a sling I felt comfortable and consequently confident with it's sort of a toss up between a Rockman and a modified pj.  Which I made would depend on what mood I was in at that moment I guess.

What about boiling up some tree sap and lining the pouch with a thin layer as not to hinder flexibility?

You could even go a step further by rubbing in some dirt into the sticky sap once it is applied. I've heard of people doing this on the bottom of their feet when without shoes. Not exactly Nike tennis shoes but hey you do what you gotta do

That's got to be the best slinging video I've ever seen. Thanks for posting that Donnerschlag. Is that you in the video?

Duct tape is the answer to lots of questions about improvised slings with solid pouch
