Osprey Packs

Syncro 12L Hydration Backpack

What Our Gearhead® Experts Are Saying:

“The Syncro 12 is that perfect in-between size—light enough for shorter rides but big enough for extra gear on epic days. The ventilation is outstanding, the reservoir setup is dialed, and the rain cover has saved me more than once when the weather flipped mid-ride.”

For riders who want to stay cool, hydrated, and organized on longer days in the saddle, the Osprey Syncro 12L Hydration Pack keeps essentials secure without adding bulk. Its AirSpeed™ suspension system combines a tensioned mesh backpanel and LightWire frame for exceptional airflow, so we stay dry and comfortable even during high-output climbs and hot conditions.

The included Hydraulics™ LT 2.5-liter reservoir provides easy hydration on the move, while a magnetic sternum strap clip keeps the bite valve secure and accessible. Thoughtful organization—including a zippered tool pocket, stretch mesh front panel, and dual bottle sleeves—ensures everything has its place, and the integrated rain cover protects gear from sudden downpours.

Built with recycled, bluesign®-approved nylon and PFAS-free DWR, the Syncro 12L strikes the perfect balance between performance, sustainability, and all-day comfort for committed cyclists.
