I bought this bra hoping it would work as a nursing sports bra.  According to the Moving Comfort rep, many nursing moms use it.  The bra fit great.  It was very comfortable and supportive when I tried it on.  I would have loved to use it for exercising, but it did not work as a nursing bra for me.  To open the front for nursing, you have to disconnect the velcro on the shoulder strap and pull the strap out of the front loop.  That's easy.  The tricky part is rethreading the strap into the loop and reconnecting the velcro.  I could barely do it with two hands looking in the mirror.  There's no way I'd be able to do it one-handed with a squirming baby on my lap.
