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.High-density, 2-layer EVA back padding; hip belt and shoulder straps with stretch fabric coverInternal zipper compartment for valuablesRope fixing strap under the flapHeight adjustable flap with internal and external pocketTrekking pole carrierDaisy chain loopLateral compression straps, can also be tensioned at front to carry gear2 strong ice axe attachmentsGear loop on hip beltHydration system-compatibleHuge front zipper access to main compartmentZipper pocket on hip beltReinforced side ski attachmentSuspension system with patented Active Spine Technology to support a natural gaitHeight of the suspension system can be adjusted with a simple movementLarge internal pocket in the front openingLarge pocket on the shoulder strap
