Two aluminium bars (1) forming an inverted „V“ plus two short fibreglass reinforced bars for additional support form the central static unit. The two fibreglass reinforced bars (2) lead from the inner aluminium frame channels laterally into the hip wings (3). The dimensions and arrangement of these reinforced bars result in an excellent combination of efficient load transmission and system flexibility. Three-part ergonomically shaped hip
strap consists of a central lumbar pad with a rubberised insert (4) to prevent the backpack from slipping, and two conically shaped hip wings. They have several layers of comfortable padding, are reinforced with a PE panel and can easily be tightened using a deflected belt strap. (5)
The technical back padding (6) consists of a number of chambers, and is conically shaped to ensure the optimum position and contact with the backpack. The load control straps (7) and the ergonomically shaped shoulder straps (8) can be attached in different positions for optimum
adjustment. The lid is also height-adjustable (9).
