We grab a rain layer, wrangle the Osprey Syncro 10 Hydration Pack from the gear closet, and head out with our hound for a day on the singletrack. Thanks to the AirSpeed suspension system and BioStretch shoulder harness, the Syncro is streamlined and comfortable on the back while being highly functional and supportive at the same time. The Syncro 10 carries just enough in the front panel compartment and zippered top pocket, and the included hydration sleeve ensures we never go thirsty. The Syncro also boasts a simple helmet carrier and integrated rain cover that's designed to keep our gear dry if we're pedaling through some afternoon showers.
