We've now tested packs from Tom Bihn, Black Diamond, Mountainsmith, and Gregory. While there's no overall winner (we loved them all), we talk about the situations we'd use each pack in.

Over a four month period, we've tested these packs on countless rock climbs, a 26 mile trail on 14,110' Pikes Peak, New York City (twice), California, Nevada, Arizona, Utah road trip, London, Madrid, multiple cities in Morocco, and Rome. We definitely have the experience to talk about what we like and what we don't.
