Whether you're headed out on a cush weekend trip filled with creature comforts or tackling a summit, our largest volume pack, the Aether Plus 100 boasts a beefier frame for big adventures and offers a stable carry that can manage the heaviest of loads. Featuring a Custom Fit-On-The-Fly Hipbelt and Shoulder Strap and a convertible top lid daypack. Constructed with high quality bluesign®-approved high-tenacity 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.
