Slope Runner 4L Vest, a running pack that offers all the storage you need to bring hydration, gels, and important gear along for the ride. Made with breathable, stretchy, and moisture-managing materials, this vest moves with you comfortably as you run through quiet pine forests and over Rocky Mountain ridgelines. An airy back panel not only offers necessary structure, but also delivers steady airflow to keep you cool and to keep the vest from feeling too hot or burdensome. Four stretch pockets in the front provide quick storage for gels and snacks, and also stash two included 500ml soft flasks to keep water close by when you need it most. A dedicated smart phone pocket, also on the chest, ensures that your phone can come along in case of emergency, while several other pockets give you stretchy storage space for packable shells, hats, and gloves. (DOES NOT INCLUDE WATER BOTTLES)
