    Berghaus Bioflex 50 + 10 backpack

    After many tours with backpack weights around 15 kilograms, I finally found a backpack in the Bioflex 50 + 10 that not only has sophisticated features, but above all effectively prevents my hip joint from hurts after days in rough terrain!

    This is made possible by the Bioflex carrying system, developed by MntHouse at Berghaus, which adapts to the hip movement and join them. So the weight is evenly distributed and reliably brought to the ground.

    carrying system

    The multipurpose and now improved carrying system "Bioflex", launched in 2004, consists of three components:

    • The Cross Load Frame is a cross-shaped aluminum frame with the hub attached to the hub, which transfers weight to it
    • Hyperlink Load Transfer System in the hip belt consists of aluminum tubes, so the hip belt is vertically flexible and horizontally stiff
    • The Bioflex Hub connects the individual systems in one joint: movably suspended, the backpack can move on two axes with the carrier. The hip movement is balanced as well as the flexion or extension of the back. So the backpack weight stays on the hip belt.

    According to Berghaus, the mobile suspension provides better weight transfer, saving energy by 10% or 3.5 chocolate bars per 6 hours of walking time.

    Myself has the system at the Djebel Sarhro Traverse saved in Morocco from hip pain, which actually set itself up after a few days of hiking through rough terrain.

    domestic equipments

    The rest of the equipment of the Bioflex is thought through in every detail and stands out clearly from the standard:

    • Two mesh pockets on the sides, one at the bottom and one more above. Very handy and often used for drinking bottle, map, GPS, energy bombs, sunglasses ...
    • I did not use the frontloader system (access to content from both top and front), but it could be handy
    • There are openings and tabs for the hydration system on both sides.
    • Pimple / pole holder with "Pole Grip", so nothing slips and is held in place
    • The buckle of the waist belt simply stuck together and wedged, which seems to me a lot more stable than the conventional method with the small parts of the buckles. 
    • I also learned to appreciate the little bag on the hip belt, whether for a camera, cereal bar or other small items
    • Rubber loops on all belts not only prevent dangling of the belts, but also reduce the risk of something becoming tangled and torn off, eg during loading actions in the bus.
    • Additional loops on the front and on the lid


    The first tour with over 15 kilograms of backpack weight - without hip pain!

    Bravo, Berghaus, and thanks for that!
