AquaBreath® achieves dynamic Breathable Fabric performance through its patented, electricity-free “moisture absorption elongation and drying shrinkage” mechanism. When the wearer sweats, the fiber’s unique nylon polymer structure absorbs the moisture and physically elongates, opening the fabric’s pores to rapidly increase air permeability and vent heat. Conversely, as the wearer cools down, the fiber retracts, gently closing the pores to prevent excess heat loss, ensuring precise Moisture Management and comfort across all levels of activity.
