This adidas running sports bra is the one you keep at the top of your drawer. Because it's the one you keep coming back to. How could you not with its supportive build that adapts to your body with a tight, stretchy fit? Not to mention the moisture-absorbing AEROREADY technology that keeps you feeling cool, dry and comfortable from start to finish. Then there's just the fact that it just looks good with an elongated shape and racerback finish. (Plus that racerback is mesh — which means extra breathability.)
