2010 also sees the same comfort and innovation integrated into a new range of hydration packs aimed at high activity outdoor sports. The Manta Series is a revolution in hydration, brought about through a simple design ethos. The Manta Series sports ergonomic and innovative features including Osprey's ‘Stow on the Go’ trekking pole attachment system and integrated raincover.

Revolutionary new design and technology means the fundamentals of Osprey’s Hydraulics packs are simple yet significant: consistent and ergonomic water delivery during periods of high activity.

Osprey HydraLock
The HydraLock system secures and squeezes the HydraForm reservoir, supplying hydraulic pressure to increase water flow and minimise water motion. Water pressure and flow is dramatically increased for quick ‘Hydraulic’ bursts of H2O whilst on the move. The full-length reservoir handle routes into the HydraLock frame, enabling easy loading when full.

Fit AND Comfort
Highly ventilated and supportive BioStretch harness and hipbelt allow free body motion with minimal pack bounce. A peripheral LiteWire frame and suspended mesh AirScape backpanel provide maximum levels of ventilation, comfort and support whilst simultaneously stabilizing the reservoir and pack load close to the user’s back.

Stability
The ventilated AirScape backpanel, LiteWire frame and Osprey HydraForm reservoir prevent ‘barreling’ or rounding out of the pack, a flat back panel providing better fit and stability during movement. The HydraLock system keeps your liquid payload in check via compressing and securing the reservoir, minimising water motion.

HYDRAFORM Reservoir
Anatomically shaped backpanel conforms to the user’s back, allowing for a more precise, stable and comfortable fit. A full-length handle prevents buckling and allows easy filling / loading. Widemouth, easy-clean Rapidfill Cap and taste-free Encapsul material provide anti-microbial protection. Articulated ‘no-leak’, on/off bite valve enables easy water flow with magnetic stowage.
