These are very comfortable.  I have had Fruit of the Loom sports bra (regular straps) since I was pregnant, and used them as nursing bras as well.  Now that's all I wear around the house, and they were getting old, so I thought I'd try these.  I'm very happy with them, they feel a little more sturdy than my previous ones, but that may just be because they are newer.  I am 36B, and these fit perfectly.  I would definitely buy these again.
