Float along effortlessly on overnight or multi-day backpacking trips. A new development in MEC pack technology allows the Aurora to carry weight like it's an extension of your own body. The Trail Motion:tm: hipbelt pivots a full 12-degrees in either direction to stop the pack from swaying and to limit the associated energy loss. Stabilizer straps let you reduce the range of motion when you’re traversing more complex terrain. Designed to fit women's torso and shoulder ratios.
