“Everything or nothing” – featuring the slogan from the breathtaking film by Mammut Pro Team Athlete Jérémie Heitz, this casual beanie will keep you warm and looking stylish on ski trips, hikes and in everyday life. The merino wool and acrylic material mix combines comfort with functionality. Mammut sources its merino wool from suppliers who place priority on animal welfare and follow mulesing-free practices. The film “La Liste – Everything or Nothing” documents the project conceived by Mammut Pro Team Athlete Jérémie Heitz, in which he skis the most spectacular 6,000 meter peaks in an unprecedented new style. This sequel to the sensational first film has once again been produced in partnership with Mammut.
