The extension is an optional accessory for your winterkumja. For close-fitting jackets and big children, the extension provides additional 10 centimeters. It is connected on the left and right side of the winterkumja and then zipped to the adapter. Therefore, the standard side covers are removed and the broader side covers of the extension are used instead.

The standard raincover does not fit Kumja plus extension. If you need a broader raincover, contact us. The extension comes in black or anthracite.

Please mind that the extension is first of all suitable for use with winterkumja. It does fit sunshinekumja aswell, but has a thicker fabric, which might be inconvenient. So, we do have an extension for sunshinekumja aswell.
