Excellent workhorse running pack - Ultimate Direction Fastpack 20 Backpack

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.
