Syncro 20L Hydration Backpack

What Our Gearhead® Experts Are Saying:

“The Syncro 20L has everything I want for long rides—airflow, stability, and easy hydration access. The AirSpeed backpanel is incredibly breathable on hot climbs, and the winged harness keeps it tight to my body when descending fast. The included reservoir and tool organization make it a complete system for full-day missions.”

For riders logging serious miles across technical terrain, the Osprey Syncro 20L Hydration Backpack blends maximum ventilation with a secure, balanced fit. Its AirSpeed™ suspension system utilizes a tensioned mesh backpanel and LightWire frame to create unmatched airflow while maintaining a close, stable ride feel. The winged BioStretch harness wraps naturally around the torso, ensuring the pack stays centered even on aggressive descents.

A dedicated reservoir compartment houses the included 2.5-liter Hydraulics™ LT bladder, which routes through a magnetic sternum strap attachment for quick access mid-ride. External organization includes a front stretch pocket for layers, a zippered tool compartment, dual side stretch pockets, and integrated LidLock helmet carry for post-ride convenience.

The Syncro 20L is built to go the distance with recycled, bluesign®-approved high-tenacity nylon and PFAS-free DWR. Combined with an integrated rain cover and compression straps that stabilize heavier loads, it’s a complete hydration and cargo solution for endurance cyclists tackling variable weather and demanding routes.
