Aarn Flow Bodypacks are the most efficient, comfortable, stable, practical and healthful way to carry load on the human body. They are a new paradigm in pack design. Based on scientific design and extensive field testing, we’ve created the best hiking and travel daypacks and bodypacks available in the world.

Mass-produced traditional backpacks significantly disturb the posture, and hinder balance and movement of the body. Backpacks create leverages on the torso that distort the natural curve of the spine. Backpacks are a stressful and energy wasting way to carry a load. Even a small hiking daypack can cause undue stress on the body.

 “For over 25 years I have been conducting international research on load carriage in military and leisure settings. This has involved a wide range of laboratory and field studies of many types of load carriage systems. Our research identified the principles of load carriage. As far as I am aware Aarn Bodypacks are the first to really put the principles into practice.”  Professor Stephen Legg, Centre for Ergonomics, Occupational Safety and Health, Massey University, NZ

Simply stated, a load carrying system for the best hiking and travel daypack should not disturb the natural posture and movement of the body. The load needs to be dispersed onto the skeletal structure in a balanced way around the vertical axis so that the loading on the body is only vertically downwards. This creates naturally balanced body friendly load carrying. Additionally, the flow motion systems of our packs ensure that body agility is not compromised. The result is naturally balanced flow motion load carrying.

These naturally balanced load carrying systems can no longer be called backpacks. We call them Flow Bodypacks, which flow with the body's motion.

A flow bodypack wraps around your body so that the weight is balanced in front and behind. Your posture and balance are unaltered by the load.

Used with our balance bags, our travel and hiking bodypacks evenly distribute weight and take the burden off of your shoulders.
