Based upon inspiration from the the Ultimate Direction Signature Series race vests, the Fastpack 20 is a streamlined, stable pack with features and capacity for multi-day run adventures, or day-long treks where you need to carry more gear. The main compartment forgoes zippers in favor of a waterproof roll top closure, allowing the pack to tightly secure everything from 15 to 23 liters. Front pockets can carry bottles, nutrition and small accessories, or you can stash up to a 3L reservoir in the rear (bottles or reservoir not included).

Customer Reviews

Comments: I love my Fastpack 20! I've used it on extended unsupported runs (160 miles of the John Muir Trail) as well as on multi-day peak bagging expeditions, and on several rock climbs and technical mountain ascents where I needed to carry a helmet, crampons, rope, harness, etc. The Fastpack easily swallows all the gear I need, yet still carries comfortably enough to run.
