PACK FIT INSTRUCTIONS (CONTINUED)
4 SHOULDER STRAP ADJUSTMENT
Tighten the shoulder straps enough to draw the pack securely against the back. AutoLift automatically engages the upper
frame of the pack. The upper portion of the shoulder straps should be floating above shoulder level at this point, leaving a gap.
Buckle the sternum loosely and position it so it sits about 2” below the collarbones. The sternum strap webbing adjusts for
position up and down by sliding on a fabric covered rail.
6 CHECK TORSO LENGTH
Locate the harness yoke—this is where the harness straps come together near the base of the user’s neck. Locate the C7
vertebra—the large protruding bone at the base of the neck. The yoke should be positioned 1 in./2.5 cm. – 2 in./5 cm. below
the C7 vertebra. When properly positioned, the shoulder straps should not slip off the sides at the shoulder or put undue
pressure on the neck.
5 SETTING TORSO LENGTH
The Torso Length Adjuster webbing runs through the two CamLock buckles on either side of the backpanel of the pack. Pull down
on the webbing loops to lower the shoulder straps just to the point where the padding of the straps makes good contact with the top
of the shoulders. Pulling too far will begin to lift the hipbelt off the correct position on the hipbones.
7 CHECK HARNESS FIT
The harness straps should wrap fully around the shoulders with no gaps between the pack and back. The AutoLift system
automatically positions the shoulder strap padding and should extend 2” or more below the armpits
8 TENSION THE STERNUM STRAP
Check the sternum strap and readjust if necessary to a position approximately 2 in./5 cm. below the collarbone and tightened
only enough pull light tension. The shoulder straps should be pulled lightly in across the chest to allow comfortable arm swing,
but not so much as to deform or lift them off the body.
