The german Y-straps

Koppeltragestell auf leder mit hilfstrageriemen fur infanterie

Pre war period the german soldier was equipped with traditional and high quality equipment. One iconic item from this period is the Model 34 tornister, the socalled "affe".  It was attached to the koppelschloss with straps and was not intended for combat use. The field gear was attached to the belt wich was supported by internal straps in the feldbluse to carry the weight. As of 18.april.1939 (HM39, no 328) the Y-straps came into use as part of a new system for infantry. The tornister was redesigned losing the support straps. The M34 was designed to be attached to the Y-straps.  As accessory the gefechtsgepack fur infanterie (A-rame) was developed. It could be attached directly to the Y-straps for combat use or to the M34 Tornister backside. 

Later developments includet various canvas backpacks replacing the mor expensive, resource consuming tornister. The Y-straps followed the german soldier to the end of the war with minor changes.

Soldier from early days of the war armed with an Mp40. The sturmgepack A-frame is attached to the sipport hooks on the back of the Y-straps.

Initially the Y-straps was issued to infantry troops, but it saw wider use as the war progressed. A belt hook similar to the one found (often missing) on the tornister secured the back to the belt. In front the hooks connected to the ammunition pouches or other gear by hooks. There were D-ring loops developed to the fasten the Y-straps to the belt, when no gear was used to attach the straps. The support straps with D-rings went under the arms and attached to the backpack the soldier was wearing. In the beginning the soldier hade the M39 Tornister attached with A-frame. The tornister carried various personal equipment and items. For combat, the A-frame detached form the Tornister and was hooked directly to the Y-straps.

The Y-straps was adjustable, both in front and in the back to facilitate the individual soldier.

As much german field gear it was not limited to a certain small amount of factories. When the military contracts was in the horizon every lederwaren fabrik started producing Y-Straps to gain a share of the new marked. The war economy created a boost for several manufacturers. A complete list of all manufacturers of Y.straps does not exist. Due to the vast number of producers, the variations in details are numerous even they follow the same design. Many producers stille exist today. "franz Brehme Walsrode", one of the common seen producers is till making lederwaren today.


In 1939 when the Koppeltragestell was introduced, resources was still availeable in germany an the war was in the beginning. The Y-straps from this period has alumium hardware and are made of high quality leather. Y-straps are carefully made with precision as can be seen with the hidden stitching, displayed further below. During the course of the war, time an resource saving changes were made. The changes can not bed dated as the nurmerous manufacturers made the changes when resources and labour became scarcer. 


As with most field gear manufacture, use of alumium is replaced by greypainted steel from 1940/41. The timing for the simplified stitching (not hidden) cannot be stated. As of 16.09-1942 firms are instructed to use the Rb.No system. On this page a Y-strap by franz Brehme dated 1942 has hidden stitching. Rb.no marked with hidden stitch can be seen but later in the war all specimens have visible stitching. As the war progressed the field grey painting of the steel aslo disappeared.
