Axis ERGO BackpackBACKPACK PRINCIPLESStabilizing the spine is necessary to prevent the vertebrae from excessive movement. A contoured semi rigid frame supporting the spine may reduce back pain by limiting motion and unloading spinal structures. The unique axilla and shoulder strap prevents forward bending of the spine and provides excellent back support. The pre-shaped internal spinal frame provides low back support and control on sideways shifting of the bag. It also transfer forces from shoulder to hips. SPECIFICATIONS1.
