Static cling is a moisture problem: fibres that hold a little water dissipate charge, while dry synthetics build it up. The best anti-static fabrics have high moisture regain, which is why natural fibres rarely cling.
Ranked on moisture regain (charge dissipation), with a penalty for charge-prone synthetics. Scores combine ISO 6741-1 moisture data with breathability, thermal, and weight attributes — recalculated at each build, with no affiliate bias.
