This innovative product series uses environmentally friendly hydrophobic semi-permeable micro-porous membrane technology to achieve waterproofing and dynamic moisture management through a unique PFAS-free formulation.The membrane is based on a polyurethane material (eco-friendly bio-based version with30% plant content) with a sophisticated pore structure that maintains breathability while creating a selective barrier – allowing air to circulate freely while effectively blocking the penetration of liquid water, Its microporous topology actively conducts heat and perspiration vapor from exercise to keep the micro-environment of the body surface dry and cool, reducing heat loss through convection.
