I have such a difficult time finding a bra that gives full support even with high impact.  This bra does the job quite well.  No bra will keep the "girls" perfectly still.  But this one comes close.  I have been using it in jump training and the "girls" and I are both happy!  The material is a little scratchy, but after I am wearing it for a few minutes, I forget about it.  I am happy with this purchase!
