Kumja is connected to your coat´s zipper. Thanks to the zip adapter system it works with almost all coats that have a zipper. Our adapter quiz will find out which adapter you need. Just enter as much details as possible and answer all the simple quenstions :)
Kumja most easily adapts to jackets that have a YKK zipper.
Zippers from YKK have a stable design and for orders from abroad (outside Germany) we recommend to choose jackets and coats that have a YKK zipper, if possible.
We have adapters that work with most other zipper brands too. However, sometimes we have to ship 2 or more adapters because we cannot forecast which one will work. So there might be additional shipping costs for returns.
