Fieldsensor® is a registered trademark of Toray Industries®. Fieldsensor® is a technical fabric designed to wick moisture through fabric construction. The spaces between fibers decrease in volume as you move from the fabric's inner surface to its outer surface. The high-volume spaces near the skin quickly absorb moisture and transport it away from the skin to the outer surface, where increased capillary action disperses the moisture for quick evaporation. Torray combined the Fieldsensor® technology with the four-way stretch of spandex for the manufacturer of form fitting garments such as bike shorts and tights.
