Syncro 20L Backpack

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.

Excellent pack.

I've used it several times

The back ventilation is the best feature about this pack, it's a huge relief especially on a hot day. That is actually the one feature I bought the pack for, I don't think I could ever go back to a pack that sits completely against the back. It is fairly large volume for a hydration pack but cinches down to be completely flat if you don't have much in it. Personally, I don't use the hydration bladder much so the two side water bottle pockets are great to have, they fit a normal bicycle bottle and are very secure. I bought the red color which has excellent visibility for when part of the ride ends up on the road. The hip pockets are tiny, so far I haven't used them for anything. Other than that I think the pockets are very thoughtfully designed. The pack stays in place while riding. The stitching and construction quality are excellent. All this combined with Osprey's guarantee makes this a great pack!
