I am still pregnant so not breastfeeding yet, but this bra has been very comfortable and appears that it will function easily once I am breastfeeding.  There is one thing I do not like about it though.  The product description lists foam-lined cups for modesty, which is a key feature I was looking for since I am wearing this pre-breastfeeding and with no nursing pads.  The foam pads are removable inserts, which doesn't bother me at all, but the inserts are cut to a smaller size than the overall cup size so you can see their outline if you are wearing a more form-fitting or lighter colored shirt.  It just looks funny.  The pads are thick enough to be 'modest' for the purpose intended, but when you see the bump and outline of the pad through your shirt it doesn't feel so modest anymore.

Otherwise I am pleased with this bra.  It is comfortable and supportive and constructed in a way that doesn't give a lumpy appearance at the back like many bras will.  I would definitely recommend it to others, just with the knowledge that you can only wear it under looser fitting or darker colored shirts.
