PACK FIT INSTRUCTIONS (CONTINUED)
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 1 in./2.5 cm. - 2 in./5 cm. below the C7
vertebra.
8 CHECK HARNESS FIT
The harness straps should wrap fully around the shoulders with no gaps between the pack and back.
The padded part of the shoulder straps should end at 2 in./5 cm. or more below the armpits without topping out.
7 TORSO LENGTH - HARNESS ADJUSTMENT
If the torso length is too long or short, the customer may need a different pack size, model or an adjustment.
Consider making an adjustment if:
• Load lifters are angled below/above 30-60 degrees
• Yoke to C7 vertebra distance is more than 2 in./5 cm. or less than 1 in./2.5 cm.
• There is a gap between the harness and back of the shoulder
9 HARNESS/SHOULDER STRAP ADJUSTMENT
If the harness is too small or large, but the torso length of the pack is correct, the customer may need a different pack size,
model or adjustment (Fit-On-The-Fly shoulder strap imaged).
10 BUCKLE THE STERNUM STRAP
The sternum strap adjusted to approximately 2 in./5 cm. below the collarbone.
