SIZE & FIT

Custom-fit backpacks are Osprey's legacy. Their expertise in designing backpacks that fit every shape, size and gender dates back to 1974, when Osprey was founded on designing custom packs for mountaineers headed to the Sierra.

As a leading brand in creating custom-fit backpacks, their pack-fitting technique ensures a properly fitting pack that maximizes efficiency, comfort and safety both on and off the trail.

SIZING OVERVIEW

Fit should not be compromised for any other considerations. Body shape and sizing varies for customer to customer. Not every customer will fit every pack. Adjustable packs allow customers to fine-tune the fit for optimal carry performance.

TORSO LENGTH / SIZING

Many Osprey packs are available in multiple sizes to fit a range of torso lengths. To determine your torso measurement, please see diagram below.

HIPBELT SIZING

To determine hipbelt size, measure around the hips at the iliac crest, not the waist. The padded portion should wrap well around the hips, leaving a gap of 3" to 6" between the tips of both hip pads when securely tightened.

Fixed hipbelt sizing
XS 24-25" / 60-114cm
S 24-25" / 60-114cm
S/M 26-45" / 65-114cm
M 27-48" / 69-121cm
M/L 28-50" / 70-127cm
L 29-55" / 72-140cm
O/S 25-50" / 64-127cm

HIPBELT ADJUSTMENT OPTIONS:

Adjustable and custom packs allow you to make sizing adjustments to the hipbelt.

PACK FITTING INSTRUCTIONS

1. POSITION THE PACK

Completely loosen the pack's hipbelt, harness and load-lifter straps. Load the pack with 10-20 lbs./4- 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 the cross-body Ergo-Pull. The padding of the hipbelt should wrap around the hips with approximately 1-3in./2.5-6cm. 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, you may need a different pack size, model or adjustment(Fit-On-The-Fly hipbelt imaged).

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. Of the torso length on the pack is adjusted correctly, the load lifters will sit between a 30- to 60-degree angle and align natually with the shoulder straps.

6. CHECK TORSO LENGTH

Locate the harness yoke - this is where the harness straps come together near the base of the neck. Locate the C7 vertebra - the large protruding bone at the base of the neck. The yoke should be 1 in./2.5 cm. to 2 in./5 cm below the C7 vertebra.

7. TORSO LENGTH-HARNESS ADJUSTMENT

If the torso length is too long or too short, you 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./5cm. or less than 1 in./2.5cm. 
  • There is a gap between the harness and back of the shoulder

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./5cm. below the armpits without topping out.

9. HARNESS/SHOULDER STRAP ADJUSTMENT

If the harness is too small or too large, but the torso length of the pack is correct, you may need a different pack size, model or adjustment (Fit-On-The-Fly™ shoulder strap imaged).

10. BUCKLE THE STERNUM STRAP

Adjust the sternum strap to approximately 2 in./5cm. below the collarbone.

WOMEN'S-SPECIFIC FIT

For more than 25 years, Osprey has been designing packs for women. We understand that body-specific fit crucial to your experience on the trail. Our women's-specific torso, harness and hipbelt ensure a proper fit to maximise efficiency, comfort, and safety. 

  • Shorter torso length 
  • Narrower, shorter harness with curves designed to accommodate most women's necks, shoulders and chests. 
  • A hipbelt designed to wrap naturally around the curves of women's hips, offering better load stabilization and support.

MOUNTAIN BIKE PACK FIT

1. POSITION THE PACK

The backpanel and harness straps should wrap fully around your shoulders with no gaps between the pack and your back.

2. ADJUST THE PACK

The padded part of the harness straps should end 1"/2.5cm - 2"/5cm below the armpits.

3. BUCKLE THE STERNUM STRAP

The sternum strap adjusted to approximately 2" 5cm below the collarbone.

MOUNTAIN BIKE LUMBAR PACK FIT

1. BUCKLE THE HIPBELT

Buckle and tighten the hipbelt using the cross-body Ergo-Pull. 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. Breathable airmesh wrap hipbelt contours over the hipbone to provide a comfortable, secure and stable carry.

2. ADJUST THE WAIST STRAPS

ErgoPull waist closure system allows for proper snug and stable fit.

TRAIL RUNNING PACK FIT

1. POSITION THE PACK

This pack anchors to the rib cage to prevent unwanted bouncing. To do this, it needs to sit higher on your torso than a typical hiking pack. When first putting on your pack, make sure the top of the pack sits just below the base of your neck.

2. POSITION DUAL CHEST STRAPS

Buckle both sternum straps, leaving the webbing a little loose for now. The top chest strap should be positioned 1-2 in./2.5-5cm. below the collarbone. The bottom chest strap can be moved up toward the middle of the harness to accommodate free and easy breathing; however, keep it down low if pack stability is your primary concern. For women, adjust the chest strap position so that it fits comfortably and keeps the pack snug.

3. TIGHTEN CHEST STRAPS

Before tightening the chest straps, make sure you have completely loosened the under-arm side body straps on each side of the pack. With the chest strap positioned appropriately, pinch the end of the webbing with your thumb and index finger and pull the strap until the tension pulls the strap from your grasp. This helps avoid overtightening the pack. Make small adjustments as necessary to ensure a secure fit. 

4. TIGHTEN SIDE BODY STRAPS

Pull the side body straps that connect the harness and pack under each arm. This will pull the lower portion of the pack against the body and snug the pack around your ribcage. Double-check the chest harness strap positioning and tension to ensure optimal fit, comfort and stability.
