Why We Like The Osprey Syncro 20L Backpack

The Osprey Syncro 20L Backpack carries everything needed to escape the maddening crowds of popular trail riding destinations. This streamlined hydration pack features a bike-specific suspension for added stability and includes a 2.5 liter Hydraulics reservoir with a magnetic bite valve for convenient drinking on the trail. The Osprey AirSpeed suspension system elevates the pack off our back for increased air circulation, eliminating the soaking-wet sensation we hate about less ventilated packs.

Hugging our body to support heavy loads, the BioStretch shoulder harness and adjustable hip belt keep bouncing to a minimum. The Synchro features various smart pockets for storing all our riding necessities, an integrated rain cover, a blinker light attachment (light not included) and LidLock helmet attachment, which conveniently holds our helmet as we grab post-ride food and drinks.
