The “Grow-Free-With-Me” body is made out of 70% merino wool and 30% silk. This high-quality, natural material is particularly gentle on the skin. It does not scratch, and feels soft almost sensitive skin. The composition of merino wool and silk ensures that your child neither sweats nor freezes. Its temperature-regulating and breathable properties are particularly advantageous for newborns, as they often cannot regulate their own temperature balance. Our "Grow-Free-With-Me" body can therefore be worn in any season. In summer, it even offers natural UV protection. As a relatively small and young brand, we consistently ask ourselves how we can make a positive and systematic change that is required and overdue in the fashion industry. We believe that animals should be treated with care, respect, and dignity. Therefore, Kalumi only uses mulesing-free merino wool. Ideally, the wool would not come from far away and straight from Germany. As the meadows for the sheep take up an enormous amount of space, sheep farming in Germany is very limited. For better or for worse, we have to source our wool from abroad as the quality also differs. Due to the different weather conditions, the quality is unfortunately not comparable since it is not fine enough and is much more scratchy.

Babies wear bodies for a duration of ten sizes. Our „Grow-With-Me“ body comes in three different sizes and only two of our sizes cover already ten clothing sizes in total. With the carefully-sourced material mixture of merino wool and silk, you only need around four changing bodies per size instead of seven when using cotton as a material. Therefore you only need 8 instead of 70 bodies for the same period of time. Our "Grow-With-Me“ body is much more resource- and environmentally friendly than conventional products as it is sustainably produced and designed to be reused, loved and shared.

That remains our little secret, but we can reveal that much: A combination of a special knitting technique and pattern allows the body to easily adjust to your baby’s height and width. The elasticity is solely achieved through the power of nature and has no added synthetic fibers such as elastane.

Our “Grow-Free-With-Me” body has to be washed at 30°C on a wool cycle and to dry flat. A higher temperature is not required as the fabric is resistant to bacteria and microbes. The reason for this lies in the structure of the wool fibre: the surface is reminiscent of roof tiles, which makes it difficult for bacteria and dirt particles to settle. In addition, the Keratin in the wool fiber breaks down bacteria itself.
