Osprey decked the Manta 34 Backpack out with all the thoughtful features that grace the rest of its Manta series and gave the pack a large 34-liter size for epic day hikes and super-light overnighters. Stuff all your needs and wants into its capacious main compartment and plentiful pockets, and marvel at how comfy and light your load feels thanks to the AirSpeed suspension system and 3D vent mesh harness. Tons of ventilation and padding reduce sticky sweat, and the included hydration system with a QuickConnect hose keeps your whistle wet, so you can keep on trucking from sunup to sundown. An included hydration reservoir brings along a whopping 2. 5 liters of water, while the integrated raincover keeps your gear protected from unexpected rainstorms.
