Glorious!!!  Keeps my breast perky and in place. I am free to yoga, eliptical plank and burpees with no breast fall out or having to frequently readjust my breast.
The racer strap option allows for decreased weight on shoulders. Such a relief!
You must, must, must lower the bra straps when you make it a racer back strap otherwise the bra will rub under your armpit and you will believe the bra doesn't fit.
