Osprey Manta 25

Manta 25 

A premiere hydration pack for light outdoor pursuits, the Manta has a lightweight design and unique drinking system that allows you to stay focused on your activity without worrying about what you’re carrying. The anatomically formed, antimicrobial and BPA-free Nalgene reservoir is easy to insert into its own dedicated compartment even when both the pack and reservoir are full.

The Manta also features the HydraLock System, Osprey’s newly launched technology that compresses the reservoir as it empties minimizing water slosh and bounce of a standard hydration system. The result is a highly dynamic, functional hydration pack that allows you to move and jump as you please without standing in your way. In terms of design and function, the Osprey Manta’s superb fit, ventilation, and water delivery is next to none in the race to the top of the hydration pack race.
