SIZING/FIT

O/S 18-22" / 46-56 cm

SIRRUS — WOMEN'S SIZING
O/S 15-19" / 38-48 cm

SPECIFIC FIT FOR WOMEN

• 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 to your body.
• The pack shape is narrower and deeper, allowing greater freedom of movement and increases 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.

FEATURES

ADJUSTABLE HARNESS
24L / 34L / 36L / 44L

1. Identify the two injection-molded adjustment ladders, which are located at the top corners of the tensioned mesh backpanel.
   1. 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.
2. 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.
3. 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.
4. 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 backpanel.

INTERNAL RESERVOIR SLEEVE
24L / 34L / 36L / 44L
Place reservoir inside sleeve to help ensure proper pack weight distribution.
Clip reservoir to buckled loop to keep upright.

INTEGRATED RAINCOVER
24L / 34L / 36L / 44L

The integrated, removable raincover provides protection in adverse weather conditions.

1. Locate the raincover icon near the base of the pack and unzip the raincover compartment.
2. Pull the raincover from the compartment and place over the top and bottom of pack using the peripheral elastic to hold it in place.
3. Reverse this process to return raincover to compartment.
4. To remove the raincover altogether, unfasten the toggle from the cord loop and remove.

Note: To prevent mildew allow the raincover to dry entirely before storing.

SLEEPING BAG COMPARTMENT
34L / 36L / 44L
Lower zippered compartment for dedicated sleeping bag storage.
The bellowed divider allows full utilization of the pack's volume when sleeping bags aren't carried.

REMOVABLE ACCESSORY STRAPS
34L / 36L / 44L
Removable accessory straps for external attachment.

1. Unclip the two accessory strap buckles.
2. Remove the webbing from the triglide at the base of the pack.
3. Reverse to reattach.

24L / 34L / 36L / 44L
Osprey's Stow-on-the-Go trekking pole attachment is designed to quickly attach and carry trekking poles while wearing a pack.

1. Locate the elasticized loop on the lower left side of pack. While pulling the loop out from the pack, insert the basket end of the trekking poles into the loop.
2. 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.
