The Trion Spine 50 makes light work of even difficult ascents requiring lots of equipment. Thanks to a suspension system featuring the Active Spine Technology and an integrated height adjustment system, the backpack allows greater freedom of movement for the shoulders and hips. This results in a more natural gait. It also ensures optimal load transfer while walking, even when carrying a heavy weight. With a capacity of 50 litres, the Trion Spine 50 has plenty of space for equipment and allows easy access through a large front opening.
