Ultimate Direction Fastpack 45

Designed for thru-hikers and hard-charging, ounce-counting adventurers, the Ultimate Direction Fastpack 45 offers the capacity and features for extended, fast-moving forays.

The pack is constructed of lightweight but durable 100D Robic Triple-Ripstop and Power Span Stretch mesh. Despite weighing just 26.43 ounces, the pack can effectively carry two full water bottles (not included), a full hydration bladder (sold separately), and a ton of backcountry essentials. Padded/ventilated strapping and edging throughout the pack body provide a comfortable fit and breathable performance. Ultimate Direction’s unique InfiKnit construction incorporates the shoulder straps and backpanel into a single, seamless piece that greatly cuts down on hot spots and maximizes comfort and fit by mirroring the contours of your body. Dual sternum straps with sliding adjustability help you to really dial in fit. A webbing waist belt further stabilizes the pack. The pack is available in Small/Medium (26"-44" chest measurement) and Medium/Large (30"-50") sizes. NOTE: When full of gear, the vest will fit smaller.

The pack offers 2856 cubic inch (46.8L) storage capacity. The main compartment has a roll-top closure that protects contents and enables the pack to cinch down to small when not filled to full capacity. Integrated side compression straps also help in load stabilization whether the pack is full or relatively empty. On the face of the pack is a large, elastic shove-it pocket that easily stows discarded layers and other essential gear. Large mesh side pockets are ideal for water bottles or other gear. On the chest portion of the harness there are multiple pockets, two of which are large enough to carry water bottles (not included). The pack also features numerous lash points, including dual low-profile daisy chain trekking pole attachments and ice axe loops.
