Piping rail for chest strap adjustment system, ergonomic

Sew-in piping rail or guide rail made of flexible TPU. In combination with the corresponding clips, it can be used to easily create a chest strap adjustment system. Thanks to the slight curvature and flexibility of the piping, ergonomic backpack straps can be produced that can adapt very well to the body. The clips can be threaded onto one end. There is a stop at the other end to prevent them from slipping out. The piping can be used for both the right and left side and can be processed with a household sewing machine.
