Most functional textiles only react once perspiration has already set in. But what if a textile intervenes before it gets to that point? An independent laboratory study by Japanese research company Skinos Co., Ltd. investigated exactly this – using a controlled crossover design, identical test materials, and precise thermophysiological measurement technology. The focus: skin temperature, heat flux, sweat rate, and peripheral skin blood flow. The results provide a solid foundation for anyone in product development or brand management looking for meaningful differentiation – beyond interchangeable moisture management claims.
