SIZING/FIT
HOW TO MEASURE YOUR BACK FOR YOUR PACK
3 TIGHTEN HARNESS
+ Tighten the shoulder harness straps to tension by pulling them down and back.
1 POSITION THE PACK
+ Completely loosen the pack’s hipbelt, harness and load-lifter straps.
+ Load the pack with 10-20 lbs/4-9 kg of gear.
+ Put on the pack and make sure that the hipbelt is centered and rests over the hipbone. The hipbelt
padding should sit halfway above and below the hipbone.
FIT
2 BUCKLE HIPBELT
+ Buckle and evenly tighten the hipbelt using Osprey’s cross body ErgoPull.
+ The padding of the hipbelt should wrap around the hips with approximately 1-3" / 2.5-6 cm
of webbing between the buckle and the hipbelt when tightened.

ACE SERIES 6
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.

ACE SERIES 7
FEATURES
RAINCOVER
1 Locate raincover icon near the base of pack.
2 Remove raincover from compartment and slip it over the top and
bottom of the pack.
3 Tighten the cord lock at the bottom of raincover to tension raincover
into place.
4 To detach raincover, unfasten toggle from cord loop.

reservoir hose in place
