ONE299 Adjustable Frame

Over recent years, the profile of the warfighter has changed to include a larger contingent of female service women, as well as a broader size demographic of personnel 

In response to this evolution the ONE299 frame was developed – an adjustable backpack frame that accommodates the smallest 1 percentile user to the largest 99 percentile – and everyone in between by using five easily adjustable configurations.

The frame is rigid in areas to provide a strong platform for large loads whilst designed to allow torsional movements in areas increasing comfort on long marches. The patented lumbar area provides increased stand-off, weight distribution and integrates with Body Armour Systems allowing ballistic plates on the rear carrier to fit into the frame, bringing the modern soldier closer to a truly integrated combat system.
