Okay the zip on my bouancy went pop over varsities and I now have the problem of where to store my every so important gear( sling, screw gate, knife and most important my camera) its is missing teeth and may need to be replaced. It is a hf serpent which are no longer made but do you think a tailor would be able to replace the zip if I poped into one? I maybe in the market to replace it as it is now three years old.
