The Osprey Syncro 20L Backpack carries everything needed to escape the maddening crowds of popular hiking and trail riding destinations. This streamlined hydration pack includes a 2. 5 liter Hydraulics reservoir with magnetic bite valve for convenient drinking on the trail. The Osprey AirSpeed suspension system elevates the pack off your back for increased air circulation, eliminating the soaking-wet sensation inherent to less-breathable packs. Hugging your body to support heavy loads, the BioStretch shoulder harness and adjustable hip belt keep pack bouncing to a minimum. This front-panel accessible pack features a variety of smart pockets for storing all of your riding and hiking necessities. Front organizer and stretch mesh pockets are great for smaller tools and snacks, giving you easy-access for grabbing and stashing items. The scratch-free eyewear pocket keeps your favorite shades and the dedicated tool pocket houses your bike tools. Another cool feature is the LidLock helmet attachment, which conveniently holds your helmet as you grab post-ride food and drinks.
