After contouring the Internal Staves and setting the Torso Length
on the Harness Shoulder Straps, put on the backpack. Adjust the
backpack position by pulling on the Harness Shoulder Straps (towards
the back of the backpack to avoid the buckles locking) and the Internal
Staves should now be following the curve of the back and the Hip
Belt will be level with the Illiac Crest, the top of the Hip Bone
below the last rib.
The curve of the Harness Shoulder Straps should now be positioned
at the centre of the chest. If this is not the case you will
need to adjust the Ladder Harness, Sliding Yoke Harness, or Independent
Sliding Harness to increase or decrease the Torso Length, and correct
the positioning of the Harness Shoulder Straps.
