PolyHD Performance Enhancing Technology
Traditional printing will close off the polyester capillary fiber from wicking moisture while dye sublimation will reduce the performance of the shirt from 40% to 60% and in some cases can completely destroy the moisture wicking property if the heat is applied for too long or at too high a temperature.
PolyHD was invented to solve both of these problems. PolyHD dyes the fiber like sublimations but without the high heat and pressure that damages the fibers. This means the moisture wicking properties remain undamaged while providing a better feel and longevity than traditional inks.
