The ideal companion: featuring the patented Active Spine Technology and an integrated height adjustment system, the Trea Spine 35 offers lots of advantages in terms of carrying. It allows the shoulders and hips to move more freely, resulting in a more natural gait. And the Trea Spine 35 can take even heavy loads in its stride. To make the backpack feel as comfortable as possible, the carrying system has been tailored to the female anatomy. One particularly practical feature is the large front opening which allows easy access to all equipment, ensuring that your belongings are within reach at all times.
