Ultimate Direction FASTPACK 15


Ultimate Direction FASTPACK 15

For the run-commuter that needs the capacity for both their running and daily gear, Ultimate Direction's Fastpack 15 has it all. Dual external mesh pockets for stashing an extra pair of shoes, a large open main compartment for multiple sets of clothing, and a sturdy laptop sleeve are all designed to keep you well organized for a smooth transition between your run and work. The roll compartment allows for the extension from the pack's 15-liter capacity to a 20-liter capacity. Rail sliding adjustable sternum straps make for a more custom fit, while side straps help to cinch down the pack and reduce movement. Alternatively, change up your loadout and hit the trails for a weekend away with this all-purpose pack.
