The Dyna 6 is a mid-capacity women's running vest with great balance, designed for long-distance runners who need plenty of room for water, clothing, food and gear. The vest cut makes it comfortable, fits great, and doesn't over-balance the load. The mesh lining ensures breathability and comfort at all times. With multiple zippered pockets made of stretch mesh in the front of the vest, you'll always have snacks and gear on hand, even when running. The top pockets hold two half-liter soft drink bottles with drinking tubes that can be routed outside or inside the vest. Thanks to the drawstring straps, you can adjust the vest to fit your body exactly, and the large elastic mesh pocket can comfortably store a waterproof jacket or hat and gloves. On the back of each shoulder, you'll find Stow-on-the-Go™ loops that can hold your running poles so they don't get in the way and you can keep your hands free. The elastic chest straps won't restrict your movement or breathing, and they're both adjustable and removable (can be unbuckled with just one hand). It is compatible with all hydrovacs. The Dyna 6 running vest is simply perfect for those who want to push their limits.
