Terraframe 3-Zip 50

from Mystery Ranch

  • $400.00

Top-loading backpacks have been around for ages, but that doesn't mean you shouldn't look for an improvement to the system. The Mystery Ranch Terraframe 50 3-zip Backpack has a triple-zipper design that allows you to open the entire front of the pack for access to all of your gear. Because different adventures require different amounts of gear, this pack has an OverLoad feature that allows you to customize your storage space by adding gear between the pack and the frame. The frame includes carbon fiber stays and tubular webbing, for structure with the flexibility you need to move, and the padded shoulder straps and waist belt make it comfortable to carry over long distances.


  • The Terraframe has rigid yet dynamic frame system that moves with you. With lightweight carbon fiber stays that flex with your body to comfortably carry heavy loads, it also features heavy-duty compression straps and load lifters to stabilize the load. With patented features and construction methods, the waist belt cants and conforms over the hips to effectively transfer and distribute the weight eliminating slippage down over the hips. 
  • Features a Redirect waist belt system that secures in a natural, forward pull direction that requires less effort to tighten.
  • OVERLOAD™ feature provides functional expandability via a load sling between the pack and the frame, allowing you to put the bulk of the weight closest to your back for optimal comfort. 
  • The patented Futura Yoke easily micro adjusts to the torso length allowing the proper amount of stand-off between the back and frame.
  • Featuring our classic 3-ZIP design for easy, rapid access to the interior.
