additional zip adapters (standard)

The Kumja jacket extension panel comes with a green zipper, which is always the same and does not fit any jacket! Kumja is connected to your jacket via adapter, which is individually chosen to match your zipper. The result is a jacket extension panel that matches your jacket only. If you want to use another jacket, you do not have to buy another Kumja but only buy an adapter, which matches that particular jacket. This way, you can use the same Kumja for different jackets. Just switch the adapter and go.
