Comfort Commute, hike or travel in comfort with Osprey’s Radial Rucksack, and enjoy active days with the AirSpeed™ ventilated trampoline suspended mesh back system, keeping you cool on the move by promoting airflow evenly across the back. A webbing sternum strap and hip belt also keep the load close, preventing movement and discomfort when weaving in and out of traffic or hiking the trails. Features For heavy gear days, the Radial can transform from a 26 to 34 litre capacity by simply unzipping the expansion system. With a LidLock™ bike system attachment, padded laptop sleeve and stretch pockets, you can also keep your gear fully organised on every adventure. An integrated kickstand will keep the pack upright when you make a quick stop and with a detachable raincover, you won’t get caught out in the showers.
