The Science of Comfort: Fit and Suspension
Torso Length
Your torso length, not your overall height, determines the correct pack size. To measure:
- Locate your C7 vertebra (the prominent bone at the base of your neck)
- Find your iliac crest (the top of your hip bones)
- Measure the distance between these points
- Use this measurement to select the appropriate pack size
Hip Belt Positioning
The hip belt should rest directly on your iliac crest, allowing 80% of the pack’s weight to be carried by your hips.
A properly fitted hip belt will:
- Wrap smoothly around your hips
- Allow for full range of motion
- Provide even pressure distribution
- Include adequate padding for comfort
Shoulder Straps
Shoulder straps should:
- Curve around your shoulders without gaps
- Not dig into your armpits
- Allow for adjustment while walking
- Include load lifters for weight distribution
