Additional ventilation channel between the Aircontact cushions.

Two Aircontact pads in special breathable hollow-chamber foam distribute the

load evenly. The Aircontact pads perform a pump effect, where-

by every movement prompts the exchange of air, resulting in opti-mum back ventilation. The result: 15% less perspiration than with

previous body-contour packs.

Flexible, tensioned Delrin® U-shaped frame

provides stability with little extra weight. It follows the most varied movements with absolute ease. The frame combines with the body-hugging fit of the pack to create a comfortable yet compact carry system with even load distributi-on and effective load transfer.

Stabiliser straps allow optimal positioning

of the backpack.

Contoured shoulder straps with 3D Air mesh lining.

Anatomically formed hip fins for freedom of movement and body-hugging carrying.

[man’s fit ]

On average, women's backs are not quite as long as men's. The SL carry system is thus slightly shorter than that of Deu-

ter's standard rucksacks. Conse quently, the models in the SL series are the ideal choice, too, for male users with shorter

backs.

This conical form is achieved by angling the belt di-agonally upwards and by

curving the SL waist belt wings. The frontal adjuster system feature of our larger volume rucksacks simpli-

fies the waist belt fitting procedure.

In order to give a perfect anatomic fit around the upper body, the SL shoulder straps are both narrower and shorter in length.

To take account of the narrower shoulder width of the female anat-omy, and thus prevent slippage, the SL shoulder straps are both narrower and shorter in length.

In general, the female waist and hip area is also shaped different-ly, so in order for the waist belt to deliver a perfect anatomic fit when fastened, it should ideally have a conical shape.

Soft edges to the straps, smaller buck-les and narrow tapered strap ends pre-

vent the SL shoulder straps from chafing under the arms and eliminate pressure

points in the chest area.

PackingThe pack’s center of gravity should sit close to the body and ide-ally at shoulder height. This way it is positioned over the body’s center of gravity and the pack won’t pull backwards. Therefore, put heavy equipment such as tent, food, big jackets close to the back in about shoulder height. Place sleeping bag, down equipment and other light objects in the bottom compartment; and midweight gear such as clothing on the top towards the outside. For easy grab, get small, often-used items in the lid pocket. Minimise the number of items you strap to the pack’s outside and evenly distribute the weight, in particular on the side pockets.

In easy terrain (hiking routes, flat trails) the load’s center of gravity should sit higher, in difficult passages (alpine routes, Via Ferrata) a bit lower and thus closer to the body’s center of gravity. This packing system leads to a more forward leaning position, yet it provides more balance.

Wrong! The pack’s center of gravity sits far from the body’s center of gravity – the backpack pulls backwards forcing the body to constantly work against the pack’s weight. The straps strongly pull on the shoulders and the wearer finds it a lot more difficult to maintain control and balance.

Our rucksacks are designed to fit the average athletic build. However, since not everyone fits the norm it is likely that women's models will fit many male users perfectly well, and vice versa. With larger capacity packs in particular, a perfect fit is crucial and for this reason the Vari-Quick shoulder straps on the regular Deuter rucksacks and children's packs can be easily swapped for SL straps in the event that the original straps are unsui¬table. Conversely, the SL straps on our SL rucksacks can be ex-changed for normal Vari-Quick shoulder straps that are suitable for the user with a more powerful build. For further information, see page 102.

Loosen all straps and put on your backpack.

The shoulder strap anchor point should ideally be positioned between the shoulder blades. Set backpacks with adjustable back-length to the correct height (Vari Quick and Vari Fit System).For small volume Deuter packs choose the right back length (Standard, SL, or EL).

Place the hip belt centrally on your hip bone, fasten and tighten.

Finally, fasten the chest strap to optimise the shoulder strap positioning.

Now tighten the shoulder straps, so that the main weight rests on the hip belt.

For big backpacks, adjust stabiliser and load adjustor straps:tighten > increased stability loosen > increased ventilationVary the load transfer from time to time between waist and shoulder.
