Two V-shaped aluminium rods (1) guide the force directly into the reinforced hip strap. The three-part ergonomically shaped hip strap consists of a lumbar pad with a rubberised insert (2) to prevent the backpack from slipping, and two conically shaped hip wings (3). They have several layers of padding and are reinforced with a PE plate. The hip strap is easy to tighten using the deflected belt strap (4). The back padding (5) is concave and sewn into chambers to provide pleasant ventilation. The height of the wide, ergonomically shaped shoulder straps is adjustable (6), and together with the load control straps (7) ensure a close, firm fit of the backpack. The Velcro-attached lumbar padding can be removed when required, in which case the system‘s aluminium rods – which are normally secured in the hip strap – are secured in band flaps. This makes it even easier to pull the rods out from the bottom when required.
