Both Kumja models have an adjustable maximum length of 70 cm.
Between the soft outer fabric (65% polyester and 35% cotton) there´s a high-quality insulation (3M™ Thinsulate™ Platinum) that keeps you warm even at extreme sub zero temperatures.
The modular velcro system lets you replace the lacing where needed or just detach it in case of babywearing. The side bars can be changed for a custom design.
The Winterkumja expands your jacket by 25 cm.
The Sunshine Kumja is has all the features of the Winterkumja, except the warm insulation. It is a good choice from about 15°C and up. Combined with the rain cover you get a waterproof extender “sandwich” that is flexibel and warmer than the light panel itself.
