The Perform Top utilises our latest environmental and sustainable high- performance fabric, EcoTech MF (multi-filament). Filament grading technology allows permanent moisture management, which outperforms traditional virgin yarns, helping you stay dryer for longer. Our engineers made this possible using a high filament count knit fabric from GRS certified yarn suppliers. We have further enhanced performance with our 100% natural seed- based wicking and resists odour with our 100% natural Mint Active anti-bacterial treatment. Bluesign approved dying facilities ensure environmental protection. Our products are anatomically designed for a run-specific fit
