zipper

This term describes a mechanical fastener characterized by the tactile sensation of teeth clicking together. It is used across a vast array of textiles, from high-fashion garments to heavy-duty industrial gear, implying a quick and secure seal that is easily reversible. In some regional dialects, particularly in British English, the term zip is more common than zipper. The word functions as a standard countable noun, referring to the entire assembly of the slider and the interlocking tracks.
