The APS back system can be adjusted in three easy stages
1. Pull down the lumbar pad, unthread the buckle and
remove the shoulder harness unit.
2. Rethread the shoulder harness unit into the appropriate
slot (highlighted by your colored line).
3. Refasten and tighten the buckle until the shoulder
harness unit is firmly situated in the slot with the arrow/white line
lining up with your colored line. Close the lumbar pad. Once adjusted
the pack is now the correct length.
