Streamlined Versatility and Maximum Ventilation
The Osprey Syncro 12 is designed for those who demand high-speed stability and exceptional breathability during high-output outdoor pursuits. Whether you are tackling technical singletrack or a fast-paced day hike, the Syncro 12 offers a streamlined profile that moves with you. The pack features Osprey’s renowned AirSpeed™ suspension, utilizing a tensioned mesh backpanel that creates a significant air gap between your back and the pack, ensuring you stay cool and dry even in the peak of summer heat.
Hydration is seamless with the included Osprey Hydraulics® LT 2.5L reservoir, featuring a dedicated compartment and a magnetic bite valve attachment on the sternum strap for easy access on the move.
