This product has been tested and approved by runners in racing conditions. The built-in vest means this bag adjusts perfectly to your shape and size. So you won’t get that unpleasant feeling of your bag bouncing around your back when you run (as with a standard bag). It also features ventilated mesh pockets at the front which can be easily accessed when running. Energy bars can be stored in the vest's chest pockets so the runner can eat on the move.
