The backpack back panel is an accessory for ourM.A.R.S. combat backpack. It is made of 1 mm thick hard polyethylene. It is also edged with a binding tape. The binding tape protects against sharp edges.
This back panel slides into the back section of the backpack. When used this way, it prevents hard or sharp objects inside the backpack from pressing against the wearer’s back. At the same time, it reinforces the backpack’s stability.
