What is micro-denier?

Micro-denier refers to ultrafine fibers that are less than one denier in thickness, with a denier being a unit of measurement for the fineness of fibers. These fibers are often used in textiles to create lightweight, soft, and breathable fabrics that have a luxurious feel. Micro-denier materials are commonly found in apparel, upholstery, and outdoor gear, as they offer enhanced durability and water resistance. Their fine structure also allows for improved moisture-wicking and insulation properties.
