This marathon running vest is constructed with waterproof polyester fabric both inside and out. Designed specifically for long-distance marathons, it dries quickly and is water-repellent. Furthermore, the polyester fabric is lightweight and soft, adding no extra weight while reducing friction during running and effectively protecting the skin.

Measuring 11.81 * 7.87 * 13.38 inches, this marathon running vest has a capacity of approximately 5.5L. It features multiple pockets, including a zippered double-layer main pocket, shoulder strap zippered pockets, a drawstring elastic pocket, and a water bottle pocket for storing items like a phone, keys, and a wallet. Cross-elastic cords are also included to secure items like umbrellas, reduce movement, and enhance stability during running. The hydration system accommodates a 1.5L , 6.19 * 14.17 inches water bladder, making it convenient for replenishing water during marathons.

The back panel and shoulder straps are made of breathable mesh, effectively reducing the sticky feeling caused by excessive perspiration during long marathons and improving carrying comfort. Furthermore, the shoulder straps feature reflective lanyards, allowing for external gear attachment and enhancing safety during nighttime runs. Two adjustable chest straps further enhance the marathon pack’s fit and stability.
