You come to the trailhead fully prepared, you expect the same reliability and readiness from your pack—and the Aether 55 delivers. Custom Fit-on-the-Fly™ Shoulder Straps, Hipbelt and an adjustable torso provide a near-perfect fit while an injection-molded backpanel offers close-to-body performance. Made with sustainable, bluesign®-approved nylon and PFC-free DWR. The framesheet maintains comfortable back contact with ventilated airflow channels and maximum stability for carrying heavy loads while the mesh-covered foam lumbar creates supportive, lightweight and comfortable contact surfaces. The extendible hipbelt allows for incremental length and angle adjustments which adds a fine-tuned fit for varying waist sizes. The Crossbody ErgoPull hipbelt pulls the pack weight into the lumbar when hipbelt is tightened for a better distribution of weight and, in turn, a better carry. The Raincover is included.
