Men’s Osprey Manta 34L backpack. Very good condition, only used a couple times before realizing it didn’t fit properly. A tensioned mesh backpanel keeps the weight off your back, enabling highly ventilated carrying comfort. Manta is designed to provide a body-specific fit to achieve maximum comfort and stability across body types.. Dedicated hydration compartment, hose port in backpanel and Osprey Hydraclip for easier reservoir hanging (reservoir not included with this item)
