The Nimbus Core introduces a new suspension system from Granite Gear that combines their Advection back panel with their Topoflex frame sheet for ergonomic weight distribution and cooling. The Topoflex frame sheet follows both the vertical and horizontal contours of the back, allowing for a more consistent load distribution leading to better blood circulation and less muscle fatigue. The suspension is The suspension is engineered with three distinct zones of flexibility--a shock absorbing lumbar zone; a semi-rigid mid-back zone for even weight distribution and the perfect level of torsional flex; and a rigid upper zone that accommodates the load lifters to pull the whole load close to your back. The Advection back panel features foam panels that allow air to flow freely between the back and the frame sheet to allow for evaporative cooling.

How to Measure Your Torso to Choose the Best Back Pack Size:
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.
Please note: Each framesheet has fine adjustment settings spaced in one inch increments to further fine-tune your fit. If you are a 17-inch torso, it is recommended to try the short torso first.
