Additional information

Our adjustable systems are based around the principle that one size can fit all. The backlength of the adjustable system can be varied to achieve a great fit on almost all sizes of people.

Adjustability is built into the Bioflex, Bioflex Light, Biofit, A-Trek & the larger Freeflow packs. These multiple systems allow us flexibility in designing rucksacks for different end uses and for a wide variety of loads.

Back length for Adjustable Systems (Bioflex, Bioflex Light, Biofit, A-Trek & Freeflow)

Back length is measured from the top of the hip bone to the apex of the shoulder (following the curvature of the body).
