About Us

Who we are and what’s important to us

Idea & Development

14 months, 20 different pocket constructions, over 160 sewn prototypes and more than 20 test carriers

By an insulin pump carrier in our environment, we became aware of the problem for the first time in 2016: Many pump wearers would like to have a comfortable, inconspicuous but at the same time beautiful solution for storing their insulin pump.

During the development, we sought support from the Charité - Universitätsmedizin Berlin, which included us in their Startup Scholarship Program in January 2017. Our pump bag panties have been developed in close collaboration with doctors, diabetes experts and pump wearers and designed with great attention to detail.

So that we can cope with the different pump sizes, wearing preferences and daily activities of the wearers, the idea arose to offer two different pocket positions.

We Value It

"Function, fashion and comfort can not be mutually exclusive"

Design - All cuts and designs are designed and implemented by us. Even if nobody sees it, we feel good when we wear beautiful underwear. Therefore, we not only think practical, but also want our customers to enjoy wearing our underwear.

Fabrics & Materials - All fabrics and elastics we use are high stretch, so there is no cut in the skin and the panties can adapt ideally to the different body shapes. All fabrics and materials are sourced from European suppliers who comply with ecological standards.

Quality & Production - When choosing materials and processing, we pay attention to high quality and sustainable quality. Our panties are produced in the European Union. In the production of our products, we attach particular importance to fair working conditions.
