Please consult our FAQ section to find answers to frequently asked questions.
The Winterkumja is anthracite, 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.
