Osprey Manta AG 28


  • You’ll find Osprey’s Manta AG™ 28 is ideal for a day hike. The Anti-Gravity (AG™) suspension system—combination of LightWire™ frame, mesh backpanel, BioStretch™ shoulder harness and AG™ hipbelt—distributes weight to keep you comfortable no matter how far you roam. Dual upper and lower compression straps help stabilize the load and provide add-on storage options if you have extra bulky gear.

    The pack’s main compartment is accessed via a front zip panel so you can see all your gear at a glance. A series of well-designed pockets keep you organized on the trail. There’s a large zippered front panel pocket with internal mesh pockets for securing small items. Dual side stretch mesh pockets provide space for extra water bottles and the hip belt has two zippered pockets for keeping trail snacks or a phone. A scratch-free zippered slash pocket provides safe harbor for your shades.

    Additional storage features include a helmet attachment loop and Osprey’s Stow-on-the-Go™ trekking pole attachment system to stash your sticks. An integrated removable raincover protects your gear if the weather rolls in.

    This pack comes with a Hydraulics™ LT 2.5 liter reservoir complete with Osprey’s magnetic sternum strap bite valve for instant access to fluids.
