A truly one-of-a-kind design, the Mystery Ranch Terraframe 3-Zip 50 combines highly durable construction, load-hauling capability, and unique modularity to create "overload" storage!

Balancing weight and strength, the pack utilizes a carbon fiber frame to deliver maximum load stability while still providing performance-enhancing torsional flex. The rear panel can actually be pulled away from the body of the pack to create an overload shelf. Excess gear can be safely stowed and comfortably carried without eating into internal storage capacity. Built-in compression makes certain that contents stay secure and stabilized. Thick padding in the shoulder straps, backpanel, and waistbelt offers supportive cushioning. Adjustability throughout the suspension system, an adjustable sternum strap, and load-lifter straps combine to let you dial in fit and maximize balance. To further ensure a proper fit, the pack is available in a variety of sizes that accommodate differing torso lengths (see the Size Chart for recommended fit range).

The pack offers innovative, "wide open" access to the interior of the 3100+ cubic inch main compartment. A 3-Zip design allows the pack to serve as a traditional top-loading pack but also enables the entire face of the pack to peel open for easy packing via a full-length vertical zipper, unpacking, and putting hands on whatever you need. This allows the top of the pack to function similar to a traditional lid and includes two smaller zippered storage compartments. There are stretch side mesh pockets and crossover compression across the front, bottom, and side of the pack that provides numerous options for lashing gear externally. Burly 330D Lite Plus Cordura fabric and sturdy YKK zippers deliver long-term durability and all-condition reliability. A lined sleeve against the frame has built-in tube-routing ports that make the pack hydration compatible (hydration system not included).
