A confidence-inspiring hike hydration pack adorned with the quality features you’ve come to expect from Osprey. The Manta 24 features an included 2.5-liter reservoir in its own dedicated hydration compartment, a highly ventilated trampoline-style AirSpeed backpanel and more than four inches of adjustability in its harness so you can tailor the fit to your specific needs. Toss aside any fears of wet contents—the Manta comes with an integrated raincover. No time to dilly dally? No problem. The Stow-on-the-Go holder lets you attach trekking poles to your pack in seconds, while zippered hipbelt pockets and mesh side pockets keep your smaller essentials within reach. An exceptional pack for long treks or long days bird-watching in the backcountry.
