WXS/S 13.5-17” / 34-43 cm
WM/L 16-19.5” / 40.5-49 cm
WOMEN’S SPECIFIC FIT
+ The unique suspended mesh located on the shoulders, backpanel,
lumbar and hipbelt contour to a wide variety of body shapes and sizes to
create a custom fit for your body.
+ The pack shape is narrower and deeper allowing greater freedom of
movement and increasing stabilization by lowering the position of the
load to a woman's center of gravity.
+ The shoulder harness is designed with different curves to create an
anatomical fit for a woman's neck, shoulders and chest.
+ Women's hips are conically shaped with a larger difference between
the waist and hip measurements. The hipbelts are shaped and angled
to accommodate this difference which allows a more comfortable load
transfer and support.

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).

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.
7 ADJUSTABLE HARNESS (TORSO LENGTH)
a. Identify the harness plugs located in one of the four sizing loops on the backpanel.
b. 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.
c. Slide the harness up or down along the LightWire rails to the appropriate torso length.
d. 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
8 STERNUM STRAP
Adjust the sternum strap to approximately 2"/5 cm below the collarbone; buckle and tighten to tension
