Running jackets vary in performance for heat retention and breathability

Recently, running for exercise and Running Core fashion have become popular, especially among the younger generations, leading to an increasing interest in running apparel. The Korea Consumer Agency (President Yoon Soo Hyun) tested and evaluated eight running jackets (from eight popular sports brands) for functionality, durability, and safety. The investigation found differences among products in terms of thermal retention and air permeability (breathability), and some products showed reduced wet resistance (water repellency) after five washes.
