SIZING/FIT
6 ADJUSTABLE HARNESS (TORSO LENGTH)
1 Identify the harness plugs located in one of the four sizing loops on the backpanel.
2 Grab the plug's pull loop with thumb and forefinger and pull the harness's LightWire extension out and to
the sides of the pack. This releases the harness and allows it to slide up and down.
3 Slide the harness up or down along the LightWire rails to the appropriate torso length.
4 There are two load-lifter ladder lock options. Correspond the lower two or upper two backpanel settings to
the lower or upper load-lifter ladder lock.
7 STERNUM STRAP
+ Adjust the sternum strap to approximately 2"/5 cm below the collarbone; buckle and tighten to tension.
5 ADJUST HARNESS
+ The harness straps should wrap fully around the shoulders with no gaps between the pack and back.
+ The padded part of the harness straps should end 1-2" / 2.5-5 cm below the armpit. And the harness
should have 1-2" / 2.5-5 cm of webbing remaining.
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 1-2”
/ 2.5-5 cm below the C7 vertebra.
+ If the torso length is too short or tall, adjust the torso length of the pack.
4 TIGHTEN LOAD LIFTERS
+ Tighten the load lifters to tension by pulling them up and forward. This will pull the pack close to body to
help stabilize the load.
