Info for customers from Switzerland

The coat extender turns your own jackets into maternity and babywearing coats.


warm jacket + Winterkumja = warm & toasty


quick: no struggle with layers of baby clothing - just put on your coat


great value: no need for special maternity or babywearing garments


flexible: use multiple jackets with our zip adapter system


Find out which zip adapter you need in our step-by-step order assistant.


Please note that Kumja works best with zippers that show the letters "YKK".
Though we do our best to provide adapters for other brands too. Please read "How does it work" for further explanations.


Please consult our FAQ section to find answers to frequently asked questions.




The Winterkumja is black, has a high-quality insulation and expands your jacket by about 25 cm with a length of about 70 cm.


It comes with a bag and a pair of black side bars that cover the zippers. You can give your Winterkumja an individual look by ordering additional side bars.


The extension panel may be washed at 30 deg.

  1. GENIAL!!

    by aurora on Aug 27, 2014

    I was really desiring an effective but nice solution for having free hands and warm baby at the same time and this is it!!
    Selection of the adapter on the web is the most difficult thing, but it is really well organized and gave to me good results (2 of 2)!
    The quality of the product, particularly of the finishes is very high, with a great value for money!
    I'll purchase a further adapter for my husband and a new Winterkumja as present!
    GREAT JOB! CONGRATULATION TO THE TEAM!!!
