Osprey’s Syncro 15 is designed for long bike rides far from the maddening crowd. Even at speed in rough terrain, the pack carries well thanks to Osprey’s AirSpeed™ suspension system. The mesh backpanel is supported by a LightWire™ frame for a cool, comfortable fit. The BioStretch™ shoulder harness works in conjunction with the built-in hipbelt wings to stabilize the load. Upper side compression straps add more stability when need be.

Front panel access to the main compartment gives you a complete view of all your gear and eliminates digging in the bottom of your pack. A small front organizer pocket and dual stretch mesh side pockets give you plenty of storage options. There’s also a zippered scratch-free pocket to safely house your eyewear and a tool pocket for trailside repairs.

An internal reservoir sleeve holds a 2.5 liter Hydraulics™ reservoir with magnetic bite valve retention. This translates to easy refills and constant sipping.

Additional details include the LidLock™ carry system to hold your helmet when it’s not on your noggin, a blinker light attachment for nighttime visibility, and an integrated rain cover just in case the weatherman is wrong.

Nearly Perfect


Spent a long time looking for a backpack that could fit necessities for commuting by bicycle, or all day hikes and off road rides. The mesh straps have a great combination of padding and breathability and the suspended mesh back prevents my back from becoming a sweaty mess and helps keep me cool. My only real complaints are the waist straps, I don't always need them so I wish there were a way to remove them or stow them, and it can be difficult to find things in the middle pocket if they're all the way at the bottom.

Love it!


Great for cycling and hiking. Very comfortable and easy to use, and put on and take off. I am 5'2", 120 lbs and the small/med is a perfect fit.

Great Pack


I've used this pack bicycling and hiking. I've tried many different backpacks over the years and Osprey is my favorite. I own two different models but this one is the most used. Great new design for the water reservoir. Easy to clean and fill.

what an awesome cycling backback


I commute to work and from work very often, one way is about 24km. I love this backback because of the compact size and how light it is. Because of the mesh back I can barely feel that the backpack is even there. I would highly recomend this backpack for cycling. The only thing that I wish is that it would come in different colors. As a female, I am not a fan of green or blue.. I got the green one because it was the only color left in the store. I would have preferred black over the very bright green, as such light green color gets dirty fast.
