The hollow Sorona, with its unique helical structure and innovative 4C hollow cross-section spinning technology, significantly improves the thermal management performance of the fabric. This design effectively slows down the increase of the fabric's heat, allowing the wearer to enjoy a long-lasting cool sensation even in high-temperature environments. By efficiently blocking the transfer of solar radiation heat to the body surface, the hollow Sorona significantly reduces the impact of external temperature on the sense of body temperature, ensuring the comfort and heat-protective effect of wearing.
