Why We Like The Big Agnes Prospector 50L Backpack

It's no surprise that Big Agnes is finally throwing their hat in the backpack ring, but we are shocked by the lightweight and earth-friendly design of one of their firsts. The Prospector 50L Backpack put an emphasis on refusing to weigh us down, so they made this pack light and made sure our gear would be comfortable balanced no matter the load. The Open Range Hip Belt threads behind the Load Wrangler back panel to transfer weight to the lumbar, and a cut-to-fit hip belt snugs up tight to prevent gaps between the body and the pack. They also added an improved compression system that pulls weight inward and upward for secure and positive load transfer.


  • First-edition pack for lightweight backpacking excursions
  • 50-liter volume ideal for fully-loaded overnight adventures
  • Recycled ripstop shell lends a hand to earth-friendliness
  • Dual-entry roll-top and duffel-style back panel zipper
