Definition of DENIER

A scale for the density (largely related to thickness) of fibers in fabric. The higher the value is, the thicker the fiber. For example, mesh athletic wear such as Badger's style B8529 use a lighter fiber (70 denier) for comfort and ease of movement, while Ultra Club’s Classic Briefcase style U1011 is made with thicker fibers (600 denier) for a stiffer fabric for durability and shape retention.
