Hi Morayfisher,
I can tell you now what the pouch is like, as I have owned several of these nets before, and I am still using one at the moment.
They are made of plastic, with a loop to put a belt through, you also have a wee strap with a popper thing on it to clip the handle in place.
These pouches are not the best and are not made to last. I have had a couple in the past that have ripped at the side of the seams. The main problem is that the pouch is a bit too small/tight for the folded net. Having said that the W.Q nets that I have owned have travelled all over with me (some hundred outings a year) I suppose with a lesser usage they would last a lot longer.
The WQ landing net I have at the moment is housed in a neoprene pouch (looks a bit like a reel pouch) which came with my guideline easy fold net.
If you liked the net, I'm sure that a more substantial holder could be knocked up, as has been said previously.
