The idea of Less waste

We believe that every action makes sense. That's why we do everything to reduce our impact on the environment: we choose natural materials, sew in Poland, employ fair suppliers. And that's why we promote the idea of Less waste: we focus on premium quality and timeless style. You can wear items from the Issen line for years, and when you decide it's time for new ones - pass them on to serve the next person. Thanks to the fact that the collections complement each other, you can easily combine new models with those you already have in your closet. 100% cruelty free. 100% comfort wear.
