Hydrophilic (water-loving) molecular chains in our fabrics middle layer (the membrane) absorb water vapor and discharges it to the outside. The higher the temperature and humidity difference, the greater the effect allowing it to dynamically adapt to every condition. At the same time, it does not allow water or wind to penetrate from the outside and protects the body from any weather. Combined with taped seams and extensive testing in accordance with high quality standards makes RE-PETE outerwear a performance functional licensed Sympatex product.
