So say goodbye to the days of contorting your body to absently fish through your jersey pockets for a bar. With a single glance the mesh top of the Vital Pack enables you to survey its contents. But if your preference is more in-line with blindly grabbing on the go say if you're packing multiples of the same bar or gel our "no fuss/no look" magnetic closure will complement your style perfectly.
