As you can see with the Mantra 20 Hydration Pack, Osprey thinks differently: to it, a hydration pack is a full system that not only quenches your thirst for optimal performance, but organizes your gear in a thoughtful manner. Though the smallest in the Manta series, it provides the full set of features, but in a lighter, more compact construction. It boasts the advanced HydraLock frame that makes packing your reservoir a breeze and a magnetic valve holder for quick and frequent sips. AirSpeed suspension and a BioStretch harness distribute and stabilize the load for maximum comfort, and plentiful pockets and organizing elements, including a padded sunglasses pocket and trekking pole carrier, keep everything tidy for speedy access.
