My son has a nylon glucose bag that is really light and comfortable, and which he really likes:

But it does not have a shock cord assembly outside – it would be useful to have one so as to be able to use a Frio bag on the outside when needed. I have been looking for the right parts and ideas to sew some such thing together on his bag, but I am not finding anything just right - neither the parts nor the right design/ tutorial. I am looking to do something more or less like this out of shock cord:

Any ideas from a sewing/ outdoors gear master?

For things like this, being durable is always more of a concern than aesthetics. So for sewing things like this, I use **braided** saltwater fishing line. Make sure you use **braided** , not regular fishing line.

Something like 40 pound test is easy to work with, but would withstand just about anything you could dish out.

Use a big needle sewing it. After you have knotted it, singe the ends first, and then paint the knot with a coat of acrylic (something like a fingernail polish). That will never come apart.

Thanks for the great tip!

What would you use for the tie-out loops to feed the shock cord through? I can’t find anything off-the-shelf that is made for the specific job.

Not sure if you are referring to the cinch assembly.

There are a lot of things like this you can pick from:  
[https://www.amazon.com/Paracord-Planet-Double-Stopper-Various/dp/B01MTFC6K4/ref=sr\_1\_3?ie=UTF8&qid=1501475222&sr=8-3&keywords=cord+cinch](https://www.amazon.com/Paracord-Planet-Double-Stopper-Various/dp/B01MTFC6K4/ref=sr_1_3?ie=UTF8&qid=1501475222&sr=8-3&keywords=cord+cinch)

If you mean just something to run the cord through, you can use a piece of canvas strap and double it over to make a loop, and sewing it down.

For the cinch assemblies, beware that some of them are not very strong. You need to find one with a strong spring to hold it securely.

On Amazon, search for “cord lock”.

That’s what I mean. I did try just folding over some strong nylon strip, but there was quite a bit of friction. I wish I could find just the right thing, something like this:

Ok, to pass the cord through without friction, either a clip attached with a canvas strap:

Or a grommet punch (if there is a free edge you can attach it to):

I post this link, not because the bag is great, (it is too big) but they have a nice and easy shock cord approach that should work for you.

And now I see on the other thread, that you already have a bag like above, and my comment is totally not needed. ☹

On the contrary! Great pic – that’s just what I am trying to craft on the LC nylon bag. But I have not been able to find nice tie-out loops to feed the shock cord through.
