    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.


The Trion Spine 35 will take even difficult ascents in its stride. Thanks to a suspension system featuring the Active Spine Technology and integrated height adjustment, the backpack allows greater freedom of movement for the shoulders and hips, resulting in a more natural gait. It also ensures optimal load transfer during all walking movements, even when carrying a heavy weight. With a capacity of 35 litres, an additional front opening and a range of features, the Trion Spine 35 offers everything an alpinist's heart could desire.
