COOLMAX® CloakFX™ fiber is engineered with an optical “masking” mechanism that minimizes the visual impact of sweat—so you never have to worry about visible sweat stains. Because the technology is built into the fiber, its “sweat-cloaking” effect is designed to last through repeated wear and washing. In addition, it delivers on COOLMAX®’s cool-and-dry promise by providing effective moisture management, breathability, and sweat masking in one product.

COOLMAX® CloakFX™ fiber may also offer higher UPF benefits than other polyester fibers in certain constructions. In ADWIN’s woven fabrics, you can expect reliable opacity—garments remain not-see-through even when wet. It also passes JIS L 1923 Anti-see-through testing.
