model changes (from may 2014)

veröffentlicht von Kerstin am 28. October 2015

We used a red zipper for the jacket extender in the past. However, it turned out to be a little too weak, as it broke occasionally. Heavy loads are put on jackets during pregnancy and with a baby in a carrier.

Since may 2014 we changed to a stronger zipper and to make it obvious we changed the color to green.

When you place an order with Kumja products, we aks you if you have any item with a red zipper. If you want to combine products with red and green zippers (e.g. order a new zip adapter for an older Kumja model), you will need the red/green adapter.

The red/green adapter adds some centimeters, as you can see below.

Comparison of different coat extender brands

veröffentlicht von Kerstin am 6. October 2015

Or: what is the difference between Kumja and other coat extenders?

  1. compatability: If you look for a jacket extender system to use your own coats for maternity and babywearing, you may want to use it for different jackets. Maybe even with all of your and your partner´s coats. Our adapter system is continuously improved so we can provide zip adapters for the vast majority of zipper types and brands. Other brands focus on YKK zippers here because these can easily be connected. In contrast, our aim is to provide solutions for all types of zippers, may it be YKK or not. Thus, with a Kumja panel you have maximum freedom to choose the jacket you want to wear.
  2. design: there are no zips visible on a Kumja extender. The zipper technology is hidden behind additional, detachable “side bars”. These can also be replaced with special designs to give an individual touch.
  3. warmth: we use highest quality insulation material from 3M (Thinsulate Platinum). Insulation tests showed that the panel keeps warmth like polar clothing (german info). If you add the optional rain cover, you will get the warmest extender possible.

Babywearing in Winter

veröffentlicht von Kerstin am 23. August 2014

Not only becomes driving your car in winter difficult. Also strollers are hard to handle when snow and ice cover the sidewalk. That is when you might realise that babywearing is a good and save alternative to pushing a pram.

Actually, wearing your baby under your jacket is the best way to ensure that your little one stays warm and cosy despite low temperatures (that is also what the “german red cross“, a humanitarian accociation officially recommends here). Without the bulk of thick clothing between you both, you can share body heat very effectively. In particular young babies can not yet control their body temperature well, since they still are used to the constant warmth level in the womb. When close to you, your baby is actively warmed, not only well isolated as in a stroller or some other container, covered with thick blankets. If you are close to him, you can easily feel if your baby is still comfortable.

You do not have to dress her in serveral layers of warm clothing. Just put on the clothes you would choose at home and wear an adequately warm coat to cover you both.

You can still close your jacket? Lucky you 🙂 You might also wear your partner´s oversized coat – not really flattering in most cases.

If your coats can not be closed anymore you might as well use a babywearing cover. The cover is put over your baby and is attached with strings and clasps. Your own jacket stays open, so it can get chilly for you. Putting on the cover and your own jacket also takes some time.

The other alternative is to wear your baby over your (winter) jacket in a thick all-in-one suit. However, using this technique your child can not profit from your body heat. Plus you will have to adjust your baby carrier to the thick layers of clothing (and adjust back again after). Using a wrap in particular is difficult when you have to deal with the bulk and often slippery fabric of winter clothes.

jacket extension for babywearingKumja the jacket extender is a quick and easy alternative. You put on your own coat with the zip-in expansion panel attached to it as usual. You and your baby are cosy and warm, you practically become one. When you get inside you can quickly put off your coat without having to get off clothing layers of your baby and get her outside the carrier for doing that.

Another option is to purchase a special babywearing jacket. Usually it provides the opportunity for back carry too. Most parents start wearing their baby on the back around the first year. However, most of the babywearing coats are not really made for low, sub zero temperatures. To us, most babywearing coats seemed suitable for the transitional season, which makes sense in economical respects. Depending on the country you live in, you might need a really warm coat only for a short period of time. That is why these special garments aim to be used oder a longer time range of the year. But might simply be too cold for winter.

Apart from that there really are nice and functional babywearing jackets that are specifically designed for that purpose. It makes sense to get one of these if you really carry your baby a lot or think about getting more than one kid.

However, back carry is also possible with the jacket extension: see “Kumja HuckePack” for details.

Aside from the jacket issue,  your baby should definitely wear a hat because most of the body heat is passed over the head which is big in relation to the body. A warm pair of socks and warm shoes make sense too, because the feet get cold quickly and are not in close contact to your body.

To sum up, it is an individual decision which solution of the coat problem works best for you 🙂
