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 organizer panel with stretch mesh dividers, and a removable fleece-lined hip accessory pouch. Streamlined single shot molded exterior is water-resistant and will not deform from wind shear. Shoulder gasket conforms to the body and increases aerodynamics. Bolstered back foam profile increases air ventilation. Soft neck shoulder straps increase comfort while riding and will not scratch helmet exterior. 360-degree reflective logo and safety piping.
