Camelbak Small Nano Vest (2 x 500ml) Quick Stow Flask For trail and ultra runners who demand top performance from minimal gear. Offering a premium minimalist hydration solution with two best-in-class 500ml soft flasks and a pack-only weight of less than 150g. The Camelbak Small Nano Vest is perfect for training and elite level racing. The vest is constructed with a 3D vent mesh which offers lightweight cushioning while promoting airflow, keeping you feeling cool and dry. Additionally, the mesh reduces the risk of chafing and discomfort, keeping your mind focused on the run ahead. Working in partnership with the vest is the 2 500ml quick stow flasks which can easily collapse to fit into a running vest, belt or even your hand. These flexible flasks have a jet valve self-seal which eliminates the risk of drips and leaks. Designed with dual sternum straps, they offer a range of adjustments for a personalised fit, keeping your comfort at a maximum. The nano vest provides multiple storage spaces for everything you might possibly need while out on a run. Firstly, a trekking pole carry is located at the back of the vest where you can easily fold up the poles for a secure fit. Again on the back of the vest is a stretch overflow pocket where you can easily reach around and quickly stash or shed a layer or rain shell. For valuable items such as a phone, wallet or keys, the vest is equipped with a secure pocket which is conveniently located for quick access with a zipper closure for added security. Lastly, two front pockets are ideal for the quick stow flasks but also can be used to store gels or other essentials you need to access quickly.
