Adjustment
The fit of a backpack, and therefore the wearing comfort, are deternined by:
1. Hip belt
- Tightened: sits close to the body, high load transfer on the hips
- Loosened: greater freedom of movement of the hips
2. Shoulder straps
- Tightened: sits close to the body
- Loosened: relieves pressure on the neck muscles
3. Chest strap
- height adjustment to shift the load locus to the chest.
- Tightened: shoulder straps sit close to the neck
- Loosened: shoulder straps sit closer to the outside of the shoulders
4. Top load control strap
- Tightened: the backpack sits close to the back for a feeling of direct contact
- Loosened: relieves pressure on the shoulders, more ventilation for the back
5. Lower adjustment strap
- Tightened: the backpack is pulled tightly to the hips for greater load transfer and better load control.
- Loosened: greater freedom of movement of the hips
Positioning the backpack correctly
- Loosen the hip belt, shoulder straps and load control straps
- Place the backpack on your back, position the hip belt in the middle of the pelvis and pull tight
- Gradually pull the shoulder straps until the shoulders feel a slight load
- Finally, tighten the load control straps depending on the type of terrain you expect to encounter, the hard the terrain the tighter the straps.
Tip:
change the setting regularly to prevent signs of fatigue
Wearing positions

- Short, padded hip flaps mean the hip belt must be worn on the waist
- Low load transfer, the backpack is firmly positioned and at less risk of moving around

- Long, padded hip flaps move the wearing position to the hips
- High load transfer
Amending the back length of backpacks
- Use the Mammut Pack Sizing tool (alternative measurement) to measure the length of someone's back. Measurement area: between the top of the pelvic bone and the bottom, protruding cervical vertebra.
- Read the size on the Sizing Tool or convert it to a size using the table.
- Set the position of the shoulder strap to the specified size, by twisting it like a bayonet fastener.
