I have been trying to find a comfortable workout bra that had a clasp in the back for a long time.  The pull over the head types are hard to get on and seem to stretch out too fast.  I've had this bra for over a month now and it is really comfortable.  It washes up great and has not stretched out.  The straps are easily adjustable and do not scratch at all. I use it most every day so plan to order another.
