Together with the US brand UNLESS, we have designed this limited edition T-Shirt to make our voice heard on International Mountain Day. The 100% plant-based Mammut x Unless Mountain Day T-Shirt contains no synthetic materials or fibers, neither in yarn, label or print, and can therefore completely decompose at the end of its life. The print shows mountains as a source of inspiration and life, as a habitat for many plants and animals, and as a place that we must cherish and actively protect. That's why all profits from the sale of your T-Shirt go to Protect Our Winters Switzerland. ...
