Issen is a casual wear line created by Nessi Sportswear brand in the spirit of slow fashion & comfortwear. The idea that sets the rhythm of our actions is encapsulated in the slogan "Feel comfort - wear comfort". We do everything so that Issen wear provides the highest degree of comfort in every situation: every day, after training, when traveling. We carefully select materials, develop the best cuts, work out the smallest detail to perfection. We combine premium quality with original design: expressive, unconventional, expressing the joy of exploring the world and admiration for the beauty that nature gives us. At the same time Issen is sustainable fashion - we act with care for nature and respect for people.

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.
