Line socks for PPC powered parachutes and paramotors

After buying several pairs of line socks and having the zippers fail, I decided to make my own. They are worlds ahead of anything on the market. The magic is in the zipper. it's a beast as far as strength but smooth as silk to operate.

So, who (built?) your line socks? Can you get a good close=up of your zipper?
