The integration of personal thermal management, perception, protection, and comfort is essential for the development for next-generation textiles capable of performing in complex environments. Janus-designed textiles represent a promising route to this integration, offering adaptive dual-functionality. However, most current designs are limited to single-purpose applications, restricting their effectiveness in truly multifunctional scenarios. Here, we present a multifaceted Janus (X-Janus) textile that overcomes these limitations by combining innovative microporous polytetrafluoroethylene fibers with multidimensional nano- to microscale fibrils and MXene-coated carbon fabric. The X-Janus textile delivers multiple energy-independent functionalities: a spectral Janus design that enables adaptive thermal management through switchable radiative cooling or warming; an electrical Janus design that provides self-powered sensing and energy harvesting; and a wetting Janus design that ensures wearing comfort with waterproofness. Besides, the textile provides comprehensive protection including chemical resistance, electromagnetic interference shielding (56 dB), ultraviolet protection (UPF > 1,500), and flame retardancy. By integrating these advanced features, the X-Janus textile inspires new strategy for self-sustainable textiles, offering scalable solutions for outdoor safety, industrial wearables, and intelligent clothing where multifunctionality and environmental resilience are critical.

Mechanisms of Heat Transfer
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...
