Keeps the 36DD girls where they need to be and doesn't give me a triangle boob in the front.  Most well supportive sports bras aren't racerback, this one is.  Please don't stop making them. Another company used to make a style like this but discontinued several years ago and I've been frustrated with the replacements. For reference this bra must function for the following workouts - Insanity, HIIT, dog walking, and the very seldom long slow run.
