SIZING / FIT
HOW TO MEASURE YOUR BACK FOR YOUR PACK
PACK FIT INSTRUCTIONS
4 TIGHTEN SHOULDER STRAP
Tighten the shoulder harness straps by pulling them down and back.
5 TIGHTEN LOAD LIFTERS
Tightening the load lifters will pull the pack close to the body and help stabilize the load.
If the torso length on the pack is adjusted correctly, the load lifters will sit between a 30 to 60-degree angle and align naturally
with the shoulder straps.
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 the pack on and make sure the hipbelt is centered and rests over the hipbone. The hipbelt padding should sit halfway above/
below the hipbone.
2 BUCKLE HIPBELT
Buckle and tighten the hipbelt evenly using Osprey’s cross-body ErgoPull.
The padding of the hipbelt should wrap around the hips with approximately 1-3 in./2.5-6 cm. of webbing between the buckle and
the hipbelt when tightened.
3 HIPBELT ADJUSTMENT
If the hipbelt is too large and “tops out” or does not offer the preferred amount of coverage, the customer may need a different
pack size, model or adjustment (Fit-On-The-Fly hipbelt imaged).

SIZING / FIT
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.

ADJUSTING YOUR PACK
TORSO LENGTH - ADJUSTING THE HARNESS
CUSTOM FIT-ON-THE-FLY HIPBELT
Completely loosen the pack's load lifters and harness straps.
To lengthen the torso length:
1 While releasing the ladder locks, located on either side of the backpanel directly above the lumbar, slide
the harness up along the LightWire frame to the appropriate torso length.
2 It is easiest to do this one side at a time, sliding the harness with one ladder lock and then the other.
3 Use the white markings on the edge of the backpanel as a guideline to align each side of the harness.
When the pack is not in use, the harness will easily slide up and down the LightWire frame. However, when
the pack is on-body, the ladder locks will engage the harness’ webbing and the harness will adjust to the
desired height.
To shorten the torso length:
1 Slide the harness down along the LightWire frame to the appropriate torso length.
2 Use the white markings on the edge of the backpanel as a guideline to align each side of the harness.
3 Tighten the webbing at the ladder locks, located on either side of the backpanel directly above the
lumbar, to tension.
The customizable hipbelt pad extends up to 6 in./15 cm. directly from the lumbar to accommodate different hip
shapes and sizes and provide a fine-tuned fit.
To adjust the hipbelt:
Completely loosen the pack’s hipbelt webbing.
1 Separate one of the pack’s hipbelt wings from the padded hipbelt by disengaging the hook-and-loop closure.
2 With one hand, hold the pack’s hipbelt wing. With the other hand, guide the padded hipbelt in/out from behind
the padded lumbar to the desired position.
3 Press firmly to re-engage the hook-and-loop closure. While slight angle/height adjustments can be made
when engaging the hipbelt wing, the white markings on the padded hipbelt should be used as the guideline.
NOTE: The rough “hook” of the pack’s hipbelt wing should always be engaged to the soft “loop” of the padded
hipbelt. If disengaged, it may rub and cause abrasion to clothing.
4 Repeat these steps on the other side. Extend the pads the same distance on both hipbelt wings so pack
weight is distributed evenly.

AETHER | ARIEL 8
CUSTOM FIT-ON-THE-FLY SHOULDER STRAP
ADJUSTING YOUR PACK
A customizable strap extension allows for the perfect shoulder wrap.
To adjust the shoulder strap:
Completely loosen the pack harness’ load lifter and shoulder strap webbing.
1 Start with one shoulder strap and separate the shoulder strap sleeve from the padded shoulder
strap by disengaging the hook and loop closure.
2 Slide the padded strap in/out of the shoulder strap sleeve to desired length.
3 Use the white markings as a guideline and press firmly to re-engage the hook-and-loop closure.
NOTE: The rough “hook” of the pack’s shoulder strap sleeve should always be engaged to the soft “loop”
of the padded shoulder strap. If disengaged, it may rub and cause abrasion to clothing.
4 Repeat these steps on the other side. Extend the pads the same distance on both shoulder straps so pack
weight is distributed evenly.
NOTE: The webbing keeper, located by the ladder lock at the end of the padded hipbelt wings and shoulder strap, aligns the webbing
before it goes into the ladder lock. The webbing coming out of the ladder lock should not be threaded through these keepers as it will
create an incorrect angle, inhibiting the straps from tightening when pulled while putting on and fitting the pack.
CORRECT: INCORRECT:
