Abstract Personal protective equipment pays attention exclusively to external safety protection and ignores the internal thermoregulation of physiological state in association with sweating. Herein, a super‐hygroscopic calcium‐doped poly(sodium 4‐styrenesulfonate) and superhydrophobic metal‐organic‐framework‐overlayed wearables (Ca‐PSS/MOF) integrated cooling wearable is proposed for special personal thermal management (PTM). Compared to the pristine fabric, the superhydrophobic MOF wearables exhibit anti‐fouling and antibacterial capabilities, and the antibacterial efficiency is up to 99.99% and 98.99% against E. coli and S. aureus , respectively. More importantly, Ca‐PSS/MOF demonstrate significant heat index changes up to 25.5 °C by reducing relative humidity dramatically from 91.0% to 60.0% and temperature from 36.5 to 31.6 °C during the running test. The practical feasibility of the Ca‐PSS/MOF cooling wearables is well proved with the protective suit of the fireman. Owing to these multifunctional merits, the sandwich‐structured cooling Ca‐PSS/MOF are expected to provide new insights for designing the next‐generation multifunctional apparel for PTM.
