Sundrop Outerwear Textiles Inc. There are two main types of zipper, coil and vislon. Vislon zippers look like a plastic tooth zipper but are really a very strong nylon.
Coil zippers have a continuous coil that runs the length of the zipper.
Both vislon and coil zippers come in a variety of weights, lengths and closures. It is important to select the correct zipper for the type of garment or closure. Below is a guide you can use to help you select the proper zipper. I recommend YKK zippers due to their high quality and strength. I tend to use the vislon zippers for insulated garments and the coil zippers for uninsulated garments.
