In climbing I do things that I enjoy and want to do not the ones that are currently in fashion.

BioFlex - Twisting Backpack by Berghaus

Innovative BioFlex backpack, BerghausBerghaus presented new backpacking revelation - BioFlex.  The result of three years of intensive development, BioFlex provides a carrying harness that allows the bag and therefore the body to flex, twist and pivot at all times on the hill.
The majority of backpacking sacs act like a splint, they are rigid and don't allow the hips or torso to flex and bend as they should when walking or scrambling.  BioFlex continuously works with the body, keeping in tune with its movements and transferring load to the hips regardless of posture and position.

Flex, Twist and Pivot
Forward Flex - the back system's lumber pad has a central pivot.  It is located within a vertical chamber that allows it to glide up and down when you bend forward, lengthening with the natural extension of your spine.
Twist - a central pivot point is stabilised by a delrin rod that runs around the sac's main frame to the hip fins.  This allows the pack to twist and mirror the forwards and backwards movement of your body while walking and the more exaggerated twisting that occurs when looking over your shoulder, scrambling or even climbing over a stile.

The flex, twist and a pivot in the hip fins work together to ensure the pack moves in a controlled manner with your body.  BioFlex provides optimum load transfer and keeps the pack's centre of gravity in tune with your own, resulting in reduced fatigue and the most comfortable carry you can get.

BioFlex is available in the new C7 series of backpacking sacs.  At the top of the range is the C7 Pro sac.  This incorporates BioFlex, along with Berghaus Dry Fusion waterproof seam technology, EVABreathe foam, a moulded occipital cavity, "finger grip" breather hip fins and materials such as Dupont Cordura® 700D.  Also available are the C7 2 and C7 1 BioFlex sacs and all come in men's and women's versions.
