Fill the backpack with a realistic weight. Loosen all straps. Shoulder the pack.
Place hip belt over the hip bones
Position the middle of the hip belt over the hip bones and tighten. If the belt sits too high, it might constrict the stomach. If the position is too low, the fins might chafe.
Tighten the shoulder straps
Now tighten the shoulder straps, but not too tight. The main weight should be on the hip belt.
The anchor points of the shoulder- straps are ideally positioned between the shoulder blades. Thus, the pads comfortably close around the shoulders.
If the position is too low, the back length is too short.
The shoulder pads, therefore, do not sit on the blades and can easily slip off the shoulders.
If the position is too high, the back length
is too long.
It sits too close to the neck, the shoulder pads run down to the arm pits – this will lead to chafing on neck and arms. Further, the pack tends to tilt back. Here, length adjustable shoulder straps will not help. Only the right back length can solve this problem. It provides full freedom of movement for your arms and relief for your upper back muscles with its anatomic, S-shaped pads. Choose the right back length (Standard, SL or EL) for small capacity Deuter backpacks. For larger models adapt the length adjustable back system (Vari-Quick and VariFlex System) to the ideal position.
Height adjustable sternum strap
Once you have found the perfect back length, fix and close the height adjustable sternum strap. Not too tight, since it could hinder breathing. The strap stabilises the shoulder straps and is a standard feature of almost all Deuter packs.
Tighten the hip belt stabiliser straps depending on the terrain. Tighten for more load control. Loosen for more freedom of movement. Tension the shoulder stabiliser straps on the shoulder straps of larger capacity packs. Loose for improved ventilation and more weight on the waist belt for easy passages. Tighter they deliver more load control and transfer more weight to the shoulder straps on rugged terrain. On longer trips, make sure you loosen and tighten all straps regularly to vary the load transfer.
To perfectly fulfil their function the stabiliser straps should be horizontally angled between 30° and 45°.
For Deuter trekking backpacks you can adjust the angle by choosing a higher or lower positioned buckle on the pack.
For smaller capacity packs, the straps fulfil a different role. They allow the fine-tuning of the back length. Loosen or tighten stabiliser and shoulder straps to perfectly fit the pack’s back position. Here, the angle can be significantly smaller or even negative.
