Deluxe Manta 34L Hydration Backpack with U-zip access and included reservoir and raincover

What Our Gearhead® Experts Are Saying:


"The Manta 34L gives me the space I need for big mileage days without going overboard. I love the internal organization, and the magnetic bite valve makes it easy to hydrate on the go. It’s breathable, balanced, and has all the premium touches I look for in a hike pack."


For high-mileage day hikes or gear-intensive outings, the Manta 34L Hydration Backpack is our go-to for breathable comfort, thoughtful organization, and built-in hydration. Designed to carry heavier loads without sacrificing stability, this pack blends premium performance with trail-friendly convenience.


We stay cool and supported thanks to the AirSpeed™ tensioned mesh backpanel and refined frame shape, while the included 2.5L Hydraulics™ LT reservoir ensures easy hydration with a magnetic bite valve for hands-free sipping. Updated fit dimensions provide a more dialed-in feel, and a redesigned front pocket with internal compartments keeps everything from tools to snacks securely stashed. A front stretch panel with a buckle adds overflow storage, and the integrated raincover keeps us ready for variable conditions. From start to summit, the Manta 34L is dialed for dependable, all-day trail performance.
