The Icon Crosswalk Backpack isn't too big or too small. It's just right, especially with the motorcycle specific features designed to make it function on two wheels. With a capacity of 18L the Crosswalk Backpack can carry your stuff for a day trip, commute to work or trip to class. Specially contoured straps are padded for comfort. The straps even unbuckle so you can more easily strap it on when you are wearing a bulky armor laden motorcycle jacket. Once you are riding, its aerodynamic shape minimizes drag at speed. Once you reach your destination the backpack can also carry your helmet.
