I bought this hoping it would be a great sports bra that I could utilize my HRM with so that I would not have to use the strap.. I was so disappointed this morning.. it was an absolute waste of money.. but it sucks because I had already took the tags off, which states, if removed or worn you can not return.  The HRM kept popping off, would not stay on for one simple movement.  For a large it still felt tight, which is weird because all my other sports bras are mediums.. This was an absolute waste of my money, that I could have used for something else!!! Wish I didn't have to even give it one star
