Useful for difficult climbs: Even experienced mountain climbers are impressed by the Trea Spine 50 and its Active Spine Technology. The integrated height adjustment provides significant benefits when the backpack is worn. Shoulders and hips move much more freely than with backpacks without Active Spine Technology. This results in a more natural gait. To increase your level of comfort, the backpack’s carrying system adapts to the female anatomy. Even heavy loads can be managed well using the Trea Spine. The large front opening provides easy access to your equipment on the go.
