Abstract Thermal and moisture balance in the body–textile microclimate is critical for human comfort, health management, and prolonged wearability. However, designing a textile system capable of simultaneously achieving sustained cooling and dynamic moisture regulation remains an unaddressed and significant challenge. Herein, a thermal and moisture regulating textile (TMRT) is developed via coaxial electrospinning, featuring a rationally designed core–shell micro/nanofiber structure with a moisture–regulating polymer sheath and a thermal–responsive polymer core. The resulting TMRT exhibits exceptional mid‐infrared (MIR) emissivity (99.82%) and low solar reflectivity (7.71%), an outstanding contact cooling coefficient (0.43 W cm −2 ), and ultralow thermal resistance (0.08 m 2 K W −1 ), enabling ≈ 6.6 °C reduction in skin temperature at 40 °C. Remarkably, the TMRT demonstrates low moisture resistance (2.49 m 2 K W −1 ) and a high water evaporation rate (0.59 g h −1 ). Furthermore, it possesses favorable moisture regulation performance and rapid humidity response, achieving a humidity–sensing resolution of 0.5% relative humidity (RH). The TMRT–based protective clothing displays a comfortable microenvironment for the human body. This work establishes a groundbreaking paradigm for advanced textiles with synergistic thermal and moisture management, addressing critical limitations in conventional protective gear, particularly in mitigating heat and humidity accumulation during prolonged use.
