Granite Gear Nimbus Core Backpack -
Granite Gear developed the unique Nimbus Core Backpack to give you easy access to larger, bulkier items. Carry your dry sacks, bear canisters, your tent, and/or a sleeping bag, as well as an odd-shaped item like a tripod, cinched down in the central easy-access storage space. Your clothing and other gear go in the full-length side zip pockets. No matter what you pack into the Nimbus Core, you’ll carry up to fifty pounds with ease thanks to the 3D TopoFlex frame that features a molded composite Y-shaped frame to offer an excellent combination of flexibility, support, and the ability to customize your fit.


  • See size chart for measurement information; torso length can be further adjusted in small increments for a custom fit, and the ‘short’ size can be adjusted for shoulder width as well
  • Two full-length lateral pockets that cinch around your gear


  • Linelock side compression straps let you easily and quickly cinch a partially empty pack to your back for greater stability and comfort


  • Two stretch side zip pockets, two stretch side drop-in pockets, and a massive front stretch pocket give you plenty of places to stash items you want easy access to
  • vertical zippered pockets


  • interchangeable shoulder strap


  • interchangeable belt
  • Advection backpanel
  • 3D Topoflex Nimbus frame/suspension system
  • Carries a bear canister securely
  • Advection back panel conforms to the shape of your back while at the same time allowing cool air to circulate
  • Floating pack lid comes off to save weight or to use it as a lumbar daypack
  • Tool loops help get your gear up and out of the way
  • unique panel loading system

There are two full length lateral pockets that cinch around whatever you place in the CORE or center section of the pack, then a compression flap can be cinched down tight holding everything securely in place. Granite Gear has found this center CORE section also works great for many other items that are hard to fit inside a conventional pack— tripods, fly rods, wet tents, as well as compressed items like sleeping bags.
When it comes to load transfer, ergonomics and airflow not all suspension systems are created equal! Most of Granite Gear's competition still use low cost HDPE plastic and an aluminum stay or two. Granite Gear's reengineered 3D TopoFlex frame is engineered to fit the topography of your back and mimic the way a back naturally flexes. The single “pivot point” attachment system on our shoulder strap and belt allow for a more precise fit and better freedom of movement while continuously supporting the load and directing it to your hips or shoulders and allowing some of the load to be carried throughout the back. Because of this system the load can be shifted to be carried by different muscle and skeletal groups. Granite Gear new Advection back panel allows for the air to flow over the back moving heat out while still maintaining significant contact and following the natural topography of the human back thus complimenting the ergonomic load carriage benefits of the TopoFlex frame and harness system.

Backcountry Edge

A unique and versatile option for true backcountry enthusiasts, the Nimbus Core effectively and comfortably carries a bear canister (not included) or other sometimes awkward pieces of gear. The modular design can efficiently haul small or large loads making the Nimbus Core a good option for day hikes or multi-day trips.
