Aquasorb is a fabric conditioner that provides moisture absorption and wicking properties to polyester, nylon, and their blends. It allows fabrics like cycling jerseys treated with Aquasorb to better absorb moisture from the body and evaporate it, improving wearability, ease of care, and comfort for the rider in varying temperatures. Aquasorb works by creating a hydrophilic surface on polyester fabrics that enables moisture absorption and evaporation, making the fabric "breathe".
