Ultimate Direction Vest Backpack : FASTPACK 40

FASTPACK WHAT'S NEW
- Optimal weight to capacity for longer adventures over rugged terrain
- Improved vest-style storage up front with a dedicated phone pocket, multiple bottle pockets, and extra gear stash pockets.
- Versatile 'suitcase' style opening main compartment with full-length three-way zipper and roll-top closure, for easy access to everything inside, no matter the stored position.
- New backpanel system (removable) combines the Infiknit™ technology with FastFlow to increase breathability and moisture wicking.

The lightweight 40.0 litre capacity UD Fastpack 40 has an optimal weight-to-capacity ratio for longer adventures over rugged terrain so you can move fast in the backcountry. It uniquely fits like a vest with water bottles up front, but distributes weight like a pack. UD gave it an upgrade with Infiknit™ and FastFlow technology to increase the backpanel'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. Bottles are not included.

The lower capacity Fastpack 30 and Fastpack 20 are also available.
