A great balance of weight and performance, the Osprey Manta AG 20 hydration pack provides storage (1220 cubic inches), houses an integrated 2.5L hydration system, and boasts an innovative, movement-mirroring suspension system. No longer do you need to settle for an ill-fitting pack in order to stay hydrated.

Osprey's Anti-Gravity Suspension system equips the pack with weight-carrying efficiency, breathability, and a contoured fit that’ll nearly make you forget you have it on your back. A broad-mesh, tensioned backpanel stretches seamlessly from the shoulder straps all the way out across the hipbelt. Though the pack maintains constant, responsive contact with the wearer, warm air can escape freely because of the separation caused between the mesh and the pack itself. Beneath the mesh, a lightweight aluminum frame provides support and distributes weight. Load lifter straps and an adjustable sternum strap further allow you to dial in fit. The pack best fits torso lengths ranging from 18”-22”.

Unlike traditional hydration bladders, the Osprey reservoir has welded baffles that minimize "barreling" by maintaining a more anatomical shape. Nestled within its own dedicated, externally-accessed compartment, the reservoir is locked securely in place, reducing the sloshing effect that many hydration pack users have come to accept as a necessary evil. The reservoir’s wide mouth is easily accessed through a patented, leakproof sliding closure that further adds speed and efficiency to refills that kids can even do themselves. An integrated PourShield makes the reservoir easy to fill and empty. An anti-microbial treatment prevents mold and bacteria from building up inside the reservoir.

The main compartment has a zippered top access point. A zippered front panel pocket and zippered pockets on the hipbelt offer quick-and-easy access to essentials. Other features include a helmet attachment loop, a safety light attachment point, and an integrated rain cover to protect the pack in inclement weather.

I like it but so annoyed.
Reviewed by Oscar D. - September 17, 2018

Likes: Fits great, love the pockets, the hydration pack is great, seems like quality materials.

Dislikes: The pack squeaks with every step I take and it drives me crazy. I have tried everything to figure out how to get rid of the squeak but with no success. I am going to return it. Such a shame bc I love everything else about the pack.
