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.

Granite Gear Sizing Chart
Torso length :
sizing and custom fitting optionsWhat torso length should I get? To find your torso length, measure the distance between your seventh cervical vertebra and the shelf of your hipbones. Do this by standing up straight with your feet shoulder-width apart. Tilt your head forward and place your hands on your hips, thumbs to the back. With a flexible tape, have someone measure from the most prominent vertebra at the base of your neck to an imaginary line drawn between your thumbs. This will be your torso length.
Cirrus, Stratus & Nimbus
Short Torso 14” to 18”
All Other Packs including Vapor Suspension Packs
Short Torso 15” to 18”
Ultralight Pack Belt - Standard equipment on all of our Ultralight Packs (except Virga) and all packs with the Vapor Suspension. This belt is a “soft” belt. It has no plastic exoskeleton like our other belts. It is lighter and more comfortable when carrying smaller loads of 40 pounds or less. Although it is our simplest interchangeable belt, it still boasts the Pivot Point connection (except on Vapor Suspension Packs), hip stabilizers, dual density foam and Schoeller Dynamic fabric. ( Not Available in XL Size)
Light Pack Belt - All the features of the Ultralight Belt plus a plastic exoskeleton that adds load bearing support. The high density plastic forms a wishbone shape that cups around your hip bone. The belt webbing is joined into the exoskeleton for an effective “wrap” around your hips. When fit properly this exoskeleton helps to keep the belt positioned right where it needs to be to transfer the weight to your hips. This belt is standard equipment on all the Light Packs.
Standard/Expedition Belt - Compatible with all Standard Packs and Expedition Pack models. It is designed to support serious loads in amazing comfort. In addition to all the features of the Light Pack Belt, the Standard/Expedition Belt is wider and sports our exclusive Cruise Control strap (pg. 14). The Cruise Control is a hip belt stabilizer strap that works dynamically to pull the load into your hips while still allowing the belt to pivot on the Pivot Point hardware. You can adjust how much you want the belt to pivot by loosening the black hip stabilizer strap and adjusting the silver cruise control. Lots of pivot works well off trail or on steep climbs and descents. Less pivot for the flats. Of course you can lock your belt to eliminate any pivoting action by simply tightening the black hip stabilizer strap. Now that’s Cruise Control!
Shoulder Strap Sizing
For a truly custom fit on our Cirrus, Stratus and Nimbus packs you can swap out shoulder straps. To find the ideal shoulder strap size, measure your chest. Shoulder straps come in two widths also. The trim fit shoulder strap is standard on most packs except the Expedition packs which sport a wide fit shoulder strap that can comfortably carry loads over 60 lbs. Our shoulder straps fit both men and women well. New this year: All short torso packs and women’s packs will come standard with a narrower pivot point attachment bar that fits medium to narrow shoulders better.
