The Instinct PX 3.1L Hydration Vest Pack frees you to race and run minimally without sacrificing comfort. Efficient storage options surround the front and back to allow for the included 600 ml flasks, a phone, gels, light jacket, and other small accessories.

You can easily personalize the fit thanks to the adjustable sternum and side straps, which eliminate unwanted bouncing. The lightweight PX Vest is made with small and large mesh patterns in order to allow for airflow while quickly removing sweat.
