Went for a 5 mile run with this yesterday and it was extremely comfortable.  The lining was very soft and I felt that the girls were held in place very well.  I know it may have the uniboob look but when I am running, I am not concerned with the look, only the comfort to me.  They were separated inside which was good.  There was minimal bounce, which also was great.  This is a good recommendation for those women with larger chests that need something very supportive for higher impact sports.
