• SL WOMEN'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 Deuter's standard rucksacks.
• AIRCOMFORT SYSTEM: On small to medium backpacks that are at home in easier terrain we go for maximum ventilation. The heart of the Aircomfort systems tested and proven for decades is its flexible spring steel frame. It is extremely durable, provides stable tension for the airy back mesh and creates the ventilation space between pack and wearer's back for the moist, warm air to dissipate. 1984 Deuter invented & patented the first mesh back system worldwide.
• ACTIVE COMFORT FIT: To guarantee a perfect fit, the backpack should sit as close to the body as possible. Thus, the weight can be evenly distributed on the entire back. The Active-Comfort-fit system achieves its fantastic carrying comfort with a stable, padded construction.
• SPRING STEEL FRAME: The round spring steel frame is very lightweight and flexible. It is extremely durable, provides stable tension for the back mesh and transfers the load to the hip belt. Its flexibility guarantees great freedom of movement and a perfect fit.
• BOTTOM COMPARTMENT: With removable separator for ideal gear access and load placement.
• POCKETS ON THE OUTSIDE: stretch pockets on the side and in the front provide additional storage space
• PADDED HIP BELT: An additional padding on the hip belt provides more carrying comfort.
• VARI FLEX SYSTEM: Deuter's Vari Flex System, leaving the generous hip fins fully mobile. The Vari Flex hip fins follow even the most complex movements allowing tricky sections to be negotiated without losing yor balance - especially important when carrying a hefty load.
• STERNUM STRAP: The sternum strap stabilizes the pack on the shoulders.
• RAIN COVER: removable rain cover with special pocket
• VALUABLES POCKET: special pocket on the inside of the pack to keep valuable items safe
• STRETCH COMPARTMENT: stretch compartment on the inside of the back to stowe sweaty/wet clothes
