Basic or Reverse? Does your zipper show its teeth? If the front side of the zipper, with the
slider and pull, shows the teeth, you have a regular coil zipper. If there is fabric covering
the teeth, it is a reverse coil zipper. At Cosmus, we use reverse coil zipper which makes
our bags more water resistant and with custom heavy duty Cosmus pullers you can feel
the smoothness while operating zip.
