WOMEN’S SPECIFIC FIT

The unique suspended mesh located on the shoulders, back panel, lumbar, and hip belt 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.

PACK FIT INSTRUCTIONS

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.
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.
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).
TIGHTEN SHOULDER STRAP
Tighten the shoulder harness straps by pulling them down and back.
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.
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.
ADJUSTABLE HARNESS (TORSO LENGTH)
- a Identify the two injection-molded adjustment ladders, which are located at the top corners of the tensioned mesh back panel.
- a. Each adjustment ladder should have four cutouts. The pack harness will pass through one of these cutouts on each ladder, ending in a plastic harness toggle, which sets the torso length.
- b To set the torso length to a different option, reach behind the adjustment ladder on both sides and lever the harness toggles until they are fully extended and straight, allowing them to pass through the ladder cutout. Once done on both sides, the harness should be free to slide up and down the LightWire frame.
- c Slide the harness up or down along the LightWire frame to the appropriate torso length and re-insert the plastic harness toggles, curved side first, fully into the matching ladder cutout on both sides.
- d Fully inserted, make sure the plastic harness toggle has been securely captured by the adjustment ladder and, under tension, is pulled up flat behind the back panel. This ensures the toggle won’t come out underweight and your torso adjustment is set.
STERNUM STRAP
Ajusta la correa para el pecho a aproximadamente 2″/5 cm por debajo de la clavícula; abrocha y aprieta para tensar.

STOW-ON-THE-GO TREKKING POLE ATTACHMENT
Osprey’s Stow-on-the-Go trekking pole attachment is designed to quickly attach and carry trekking poles while wearing a pack.

A. Locate the elasticized loop on the lower left side of the pack. While pulling the loop out from the pack, insert the basket end of the trekking poles into the loop.
B. On the left harness strap locate the trekking pole icon. Pull up on the cord to open, place pole handles in the loop and tighten with the cord lock to secure.
C. Reverse these steps to remove the trekking poles.

A. Slide the tool shaft through the top of the ice tool loop and flip the shaft up toward the top of the pack.
B. Loosen the bungee cord lock and route the tool handle through the bungee. Tighten the cord lock nesting it into the Y-clip to secure the tool into place.
