Koppeltraggestell für Infanterie (WH/LW Combat Y-straps)

The combat Y-straps were developed in April 1939 along with the M39 backpack to replace the earlier M34 backpack with integral shoulder straps. The combat Y-straps were also utilized with other backpacks including the A-Frame Assault pack and were designed to assist in distributing the weight of the equipment carried on the load bearing waist belt to the shoulders.
