Ultimate Direction Fastpack 20

1 item left

This lightweight Fastpack 20 allows you to move fast in the backcountry with a durable design that checks all the feature boxes. True to our roots, it uniquely fits like a vest with water bottles upfront, but distributes weight like a pack. We gave it an upgrade with Infiknit™ and FastFlow technology to increase the back panel's breathability and moisture-wicking. This do-it-all pack also has plenty of dedicated external storage, a roll-top opening, and a full-side external zipper for easy to anything inside.
