You will hardly feel this 4L running pack that offers plenty of space to stash nutrition and weather-protective gear needed for steep mountain runs. Lightweight at only 204 grams, but with features such as a waterproof pocket and a simple stowage system for front-carry water bottles. Special stretch mesh pockets carry gels or flasks, and a zip pocket holds valuables. Add an easily adjustable front closure and the Vertical Running Pack turns into an essential companion.
