While most lightweight performance fabrics reveal sweat at the first sign of dampness, Vanisher™ disperses moisture to make it virtually sweatproof. Proprietary sheath-core polyester yarn engineered with titanium oxide delivers opacity that outperforms full-dull and semi-dull yarns. Vanisher™ compression fabric also delivers strong thermal resistance, with lamp testing showing up to 3°C / 37°F lower surface temperature compared to identical constructions in standard yarns, and high UPF protection for long summer efforts.
