The beautiful Bergans of Norway Glittertind 70L is built around the revolutionary spine suspension system: A double-helix-shaped spring steel frame holds it together, allowing the hips and the shoulders to twist and move independent of the torso, like your spine (think of a twist in yoga). But it's not just the tech we loved about this pack. Its sleek architecture, with a detachable top lid and half-zip front entry, made it easy to access gear packed deep inside without taking up too much valuable space. [$260;]
