Removing top lid reduces carry capacity by 9 L and weight by 80 g. Internal hydration sleeve with center back hose port and Osprey Hydraclip for easier reservoir hanging. Internal compression strap keeps loads stable. Large front fabric compression pocket with stretch side panels accommodates overloads. Multiple front panel lash points for securing extra gear.
