Thicker fibers tend to be more durable and abraison resistant.
But newer, lighter fabrics, that incorporate tear and abraision resistant processing allow, lighter materials to be used for some applications. The thickness of fibers that make up a particular cloth is expressed as denier . The higher the number, the thicker, heavier, and more abrasion-resistant the cloth. Most pack cloths begin at 420 denier. The higher the denier the stronger the material but this also leads to heavier overall pack weights.
