The CamelBak Octane 9 hydration vest measures 15.6 x 10.2 x 7.1 inches and weighs 12 ounces. Designed specifically for a woman’s frame, the CamelBak Women’s Octane 9 Hydration Pack is comfortable, functional, and engineered for excellence. It is designed with our best-in-class Crux reservoir that holds up to 2 liters of water. For extra hydration, we’ve added several harness pockets that are perfect for our Quick Stow flasks. The CamelBak Octane 9 Vest is built with a 3D mesh vent that offers lightweight cushioning while maximizing airflow and reducing the risk of chafing for a cooler, more comfortable, and more enjoyable run. The CamelBak Octane 9 hydration vest provides integrated organization that allows you to keep all your small essentials safe and easy to find. Trekking poles can easily be folded and fitted to the vest securely and can be easily removed even while running. Reflective details on this vest keep you visible during those early mornings or late-night rides, and the stretch overflow pocket is the perfect storage space for bigger items like rain shells. The fuel and gear storage spaces are ideal for gels or energy bars and are specially designed so that Quick Stow flasks fit perfectly. An additional tube trap keeps your tube secure and easily accessible for quick hydration.
