The Trion Spine 50 makes light work of difficult alpine ascents requiring lots of equipment, from axes to skis to ropes to avalanche safety gear. Thanks to a suspension system featuring 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 load. With a capacity of 50 liters, the Trion Spine 50 has plenty of space for equipment and allows easy access through a large front opening.

The Trion Spine is loaded with attachment options and pockets, such as an internal zipper compartment, dedicated bladder sleeve, and a large internal pocket in the front opening. On the outside of the Trion you'll pockets on the shoulder strap and hip belt, a reinforced side ski attachment, gear loops on the hip belt, and ice axe attachments.
