Freeflow

Freeflow was developed to address a persistent constraint in load-carry systems:

Suspended mesh improves airflow but introduces instability under load.
Close-to-back systems carry efficiently but restrict ventilation.

The objective was to maintain a consistent, controlled air gap without compromising load transfer to the lower body.

This required separating two functions that are typically coupled: ventilation and structural load transfer.

The system introduces a defined lumbar interface that anchors into the lower back and pelvis, allowing load to transfer into the body’s primary support structure while the main pack body remains offset to enable airflow.

To achieve this, custom 3D-printed lattice lumbar pads were developed.
The lattice structure provides local compliance for comfort, while remaining open enough to maintain airflow and resist collapse under load.

The result is a system that maintains airflow without sacrificing load stability or control.
