The absolute best is a two-part answer: Lilypadz and Lansinoh. You re-use the lilypadz. They are silicone, so very easy to use. But I found that I still leaked... it was just contained in the pad. When I removed the pad, there was a small waterfall! When I didn't want to deal with it, I used Lansinoh pads. They do not show through clothes, are very absorbant, and you can get them anywhere. They're awesome!
