With every MAMMUT product sold, we support Carsten Stahl's "Stop Bullying" initiative. Sport has always been a way to find a way out of difficulties and social injustice or to reduce aggression. The work of Carsten Stahl convinced us. It is where it burns and is particularly dangerous: among children and adolescents. He travels from school to school with his program and explains. Loud, direct, but just as sensitive. The kids listen to him because he goes to their eye level. Together with Carsten Stahl, MAMMUT sets an example!
