I use the Gerber washable pads. They have a moisture resistant barrier, and I haven't leaked through them. They are, however, a bit on the small side, and can move around a bit in the bra (I'm a 42F, so it may just be that the pads are too small for my big girls :oops: ). I find that at night I have to use something larger because I leak around them when they move, so I use the disposable ones then.
