It has gained the titles of "indestructible" and "custom-made." That's how it will stay, although the popular trekking backpack is now up to 15% lighter. The new, ergonomically shaped hip fins flow into the back construction and literally embrace the body. This allows even heavier loads to be carried easily and close to the body's centre of gravity. In addition, nature loving hikers and trekkers can store everything they need, from their tent to provisions. On top of that the Aircontact, which is also a great travel backpack, lets you use its lid as a separate, detachable small backpack.
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.
