anyone that is interested can of course have one too!you can feel free to pick your own font type that fits best to your bike, same with the material and print colors.
the material is neoprene and it is available in different sizes and colors.
to check the colors go here: http://www.zwosix.de/ikss.html" onclick="window.open(this.href);return false; and hover over "Farben", for the print the same colors are available plus white and yellow.
for the needed size check the circumference of your chain stay.
the price is 13.95 Euro plus shipping costs (shipping should be pretty cheap because of the really low weight), depending on the amount I can maybe get a cheaper deal.
here are some examples: http://www.zwosix.de/galerie.html" onclick="window.open(this.href);return false;
P.S. if anyone doesn't know what a frame sock is: it's wrapped around the chain stay and protects the frame from hits by the chain (such hits appear during normal biking but of course especially during a "chain suck" where the chain jumps off the smallest front cogwheel.
here you can see the frame sock I am using at the moment, it's that part with the "NC17" print:
