This pack is a minimalist's dream, and scored the best of all the packs in weight and versatility. With a simple top-loading design opening into a single compartment, this pack remains comfortable during a myriad of activities.
The Flash 18 is an awesome lightweight pack that is less hiking specific pack than any we tested, but can most certainly transition between just about all of your activities, especially if you're on a budget and need a pack to take you from urban life to the mountain then to the crag. This pack climbs well due to its narrow profile, and is a great option for multi-pitch days and summit attempts.
If you want something more substantial but still lightweight, check out the Deuter Speed Lite 20.
