The exterior design balances fashion and practicality, with a simple sleeveless round neck silhouette and smooth side seam lines that outline a sleek and sporty silhouette. The contrasting splicing technique breaks the monotony of solid colors, and the available color combinations include vibrant orange black, cool gray blue and other trendy combinations, which not only meet daily training needs, but also are suitable for wearing directly out of the street after exercise. The back hollow design incorporates aerodynamic principles, forming natural wind resistance channels during acceleration running, further improving heat dissipation efficiency, while showcasing the muscle lines of the back, creating a sporty look full of strength. Whether it's daily jogging, gym training, or outdoor off-road challenges, this vest can help break through the limits of sports with outstanding performance, interpreting the new trend of summer sports fashion in 2025.
