nexttoskin

Next-to-skin, often written as nexttoskin, refers to garments designed to be worn closest to the body as the innermost layer of clothing or equipment systems. In textile engineering and apparel design, next-to-skin fabrics are selected for properties that promote comfort and performance, including moisture management, thermal regulation, and low bulk.

Materials commonly used include synthetic fibers such as polyester and nylon, often blended with elastane for stretch, and natural fibers such as merino wool. Fabric technologies include moisture-wicking, quick-drying finishes, thermal regulation through lightweight knit structures, and antimicrobial or odor-control treatments.

Construction emphasizes a snug, close-to-body fit with minimal bulk. Fabrics are often lightweight and may be seamless or use flat-locked seams and tubular knitting to reduce chafing. Care guidelines usually call for gentle washing and low-heat drying to preserve fiber performance.

Applications include athletic and outdoor activities such as running, cycling, skiing, and hiking, where a next-to-skin layer helps manage sweat and regulate temperature. Medical and occupational uses include compression base layers designed to support circulation and comfort in long-duration wear.

Environmental and lifecycle considerations are increasingly addressed via recycled fibers, responsible dyeing practices, and durability-focused design. Consumers may look for certifications such as Oeko-Tex Standard 100 or Bluesign when evaluating next-to-skin fabrics.
