These pads are not too thick, but depending what you wear, you may still see the fold line of the pad through your shirt. The only other nursing pad I tried was J&J, which I didn't like at all because of their thickness, lack of adhesive, and they always made it look like you could see your nipple bump! These nursing pads always stay in place--even when I wear a nursing sleep shirt, which is looser fitting than when wearing a tank or bra. They are individually packaged which is great for travel and keeping them clean, not so much for the environment. Also depending on your cup size (I'm on the smaller size), they can be on the large size as far as total size. Overall, I highly recommend as I didn't feel the need to keep searching for another brand after I found these.
