Backpack webbing help

[Black Phoenix]

Hello everyone
I wanna design and make a Backpack. While I have come quite far with the design I dont quite know how to make the sides of my design in a way that is durable. The back is fully made out of veg tan buffalo ginde (4mm thick)
I drew a model of my bag on my pc to upload. The 3 drawings are from the side, top down and from the front. The Idea is having the outside wall about 3 cm inwards and then have a kind of net from paracord between the two sides. That way stuff can be stored behind the net. I hope it makes at least a litte sense. How can I implement this without the paracord slowly riping the leather over time? The backpack is supposed to be durable and last many many years.
Thanks in advance for every answer.

You could use sail eyelets and run the cord through them

how do those hold up long term
there will be weight pulling on them when the net is loaded
do i need a special tool to put them on

If installed properly they can take a lot of beating. You need a special tool to install them. It is like a tapered punch that goes into a tapered hole. At least for very big ones.

You could also use some small D-rings for the paracord.
On your picture #2, the black stitch on the left (closest to the edge of your bag) - every 2" (give or take), you mount a D-ring. The D-ring can be mounted using either a thin strip of your leather or a strip of webbing. You can get D-rings in many sizes and colours, I would think that a 5/8" D-ring in brass would look good. 

Something sort of like on this picture:
