    Fair Wear

    Mammut strives to ensure fair and safe working conditions in all factories making its products. To systematically improve working conditions throughout its supply chain, Mammut was the first outdoor brand to join the Fair Wear Foundation.


Inspired by Mammut’s active lifestyle approach. The backpacks from the Seon line are designed to combine work and leisure: They include a dedicated "work" section for a laptop, tablet or documents and a "climbing" section for sports equipment. You get to stay mobile and enjoy your free time. The modern roll-top lock of the Seon Courier makes it particularly useful for bike commuters – you always have access to your belongings. For destinations further away, you can attach the Courier to your trolley case via a practical loop.
