Fly Fishing Landing Nets

How I can connect my landing net my Fly Fishing vest?
I know that magnetic emissions are large, but I really do not want drop the twenty dollars in one if there is a simpler solution.
I just stick the handle of the network behind me between the collar of my jacket and shirt. Sometimes I get behind me on my waist. Then all you have to do is reach back and grab it. Be sure to add a couple network of times after using it to get the water from it.
