The Ultimate Run bra is designed just for running, and reduces bounce by 78%, which is much more than Berlei! The double layer means you can wear this as a top, and it even has reflective tape across the front for visibility at night. The racerback style means that you have to put it on over your head. No twisting around at the waist (which is SO bad because it stretches bras really quickly). Just so you know, Shock Absorber bras regularly win awards and this one is no exception.
