The APS back system can be adjusted in three easy stages
- Pull down
the lumbar pad, unthread the buckle and remove the shoulder harness
- Rethread the shoulder harness unit into the appropriate slot
(highlighted by your colored line).
- 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.
