The Osprey Aether 65 Extended Fit Pack - S/M was designed to provide a stable close-to-body carry, ideal for a week plus on the trail or a weekend carrying a lot of gear. With incremental length and angle adjustments, this pack is designed to fit up to 70-inch hips with an extended hip belt. The Fit-on-the-Fly hipbelt integrates the LightWire frame into the adjustment system to create better distribution by pulling weight into the lumbar when tightened. The adjustable torso length gives a fine-tuned fit for a variety of body shapes and sizes. The Custom Fit-on-the-Fly shoulder straps give precise shoulder wrap and fit with spacer mesh fabric that is soft and comfortable as well as longer sternum straps. The injection-molded die-cut foam Airscape back panel ensures a breathable and comfortable close-to-body fit with ventilated airflow channels and mesh-covered foam lumbar to give support. The Aether 65 is an excellent fitting pack that can help you carry larger and heavier loads.
