This bra has been a reliable tool in my world. I own at least 5-always.  I am a very physical person.  Between cycling to work, yoga, the gym, or sitting reading a book  I am usually comfortable, and confident nothing is popping out.  I am a 38E woman, so I was thrilled to find Moving Comfort.  It isn't everything I would like in a bra, but short of designing my own (or getting a reduction).  I am perfectly happy with it.
