Osprey has been working on this design for a long time, and they've finally released the animal into the wild. The Hydraulics line by Osprey features an anatomically shaped reservoir that conforms to the wearer's back for a perfect, comfortable fit. The Manta 20 pack, like the entire Hydraulics line, includes the Osprey/Nalgene reservoir which is taste and odor free, BPA and PVC free, and contains the AquaGuard anti-microbial formula to prevent bacteria and mold. Cargo space isn't affected by the reservoir either, thanks to the HydraLock frame. Not only is there a separate compartment for the reservoir, but the HydraLock frame gives it a little pressure which increases water flow and keeps the water from sloshing around.
Fast and light endeavors are perfect for the Manta 20 hydration pack. Incorporating a streamlined design along with all the key features of its larger siblings, this pack is perfect for light and fast hikes, adventure racing and full day trans-alpine mountain bike rides.
The green to yellow zones represent the recommended load range for this pack.
