2010 sees Osprey’s expertise in comfort and innovation integrated into a new range of bikespecific hydration packs. The Raptor Series features an innovative, ergonomic backpanel, providing superb bike-riding comfort. Bike specific organisation pockets hold your gear securely and helmets can be stored using their exclusive LidLock system.

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. The full-length reservoir handle routes into the HydraLock frame, enabling easy loading when full. Water pressure / flow can be dramatically increased when the user’s back is arched (when riding) for quick ‘Hydraulic’ bursts of H2O.

Fit & Comfort
Highly ventilated and supportive BioStretch harness and hipbelt allow free body motion with minimal pack bounce. An AirScape ridged foam backpanel, Osprey’s new anatomically-shaped HydraForm reservoir and HydraLock frame provide all-day comfort, fit and support whilst stabilizing the reservoir close to your back during periods of high activity.

Stability
The ridged EVA foam backpanel and HydraForm reservoir framesheet prevent ‘barreling’ or rounding out of the pack, a properly contoured back panel providing better fit and stability during movement.The HydraLock frame system keeps your liquid payload in check via uniformally 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.
