The NEW Mach S Motorcycle Backpack is re-engineered to be smaller in overall size (by 15%) than the Mach 5, Ogio's top selling rider's performance pack, while maintaining all the high performance features that this bag is known for. This fully-loaded Mach bag is still the most comfortable, functional and aerodynamic riding pack on the market. The large, expandable main compartment features adjustable load dividers, deluxe organiser panel with stretch mesh dividers, and a removable fleece-lined hip accessory pouch.
