This innovative construction optimizes comfort and keeps you dry, enhancing your running experience.
        • Ventilation Hole Design: The strategically placed Ventilation Holes not only enhance airflow and heat dissipation but also improve adhesion, preventing slippage during strenuous activity. This ergonomic design ensures a secure and comfortable fit.

        Craftsmanship
        • High sewing standard with a minimum of 8 stitches per inch for reinforcing every seam, making the bag more durable and doubling its lifespan.

          This process increases the tensile strength of each seam by at least 30%, making the seams less prone to breakage under a minimum tensile force of ❶7 kilograms. Compared to traditional processes, the lifespan of WATERFLY bags is extended by at least 50%.
        • Reinforced connection points at all stress areas.

          + Straps Reinforced Stitching.

        • Built with platinum-grade buckles engineered for a minimum of 50000 use.

          Each buckle is designed to support a minimum of 45 kilograms of force and built to withstand temperature as low as -20 degrees Celsius / -4 degrees Fahrenheit without compromising its strength and durability. With an average usage of 15 times per week, the buckles can last up to 70 years.
        • Built with platinum-grade SBS zippers engineered for a minimum of 10000 use.

          Each zipper runs smoothly, ensuring a seamless opening and closing experience. Each zipper is designed to withstand a minimum of ❺10000 pulls and offers at least three times the lifespan of ordinary zippers. With an average usage of 15 times per week, the zippers can last up to ❻14 years.
