Utilizing the same suspension as Granite Gear's award winning Nimbus Trace Access 70, this downsized version will also carry an impressive amount of weight comfortably. The access panel makes organizing your gear easy and the maple-core framesheet will keep the weight transferred to your hips for all day comfort. Granite Gear's 3D TopoFlex frame is engineered to fit the topography of your back and mimic the way a back naturally flexes. The single âPivot Pointâ attachment system on our shoulder straps and belts allows not only a more precise fit and enhanced freedom of movement; It supports and more equally redistributes your load along your hips, shoulders, and back! Now made with a maple-core, composite laminate which is both lighter and offers more longitudinal rigidity. Their Advection Back Panel compliments the ergonomic carriage benefits of the Topoflex gram and harness system by encouraging heat transfer and dissipation while simultaneously using the natural symmetry of the back.
