I bought 3 used ones but they are the new style with the fabric laminated. The laminate is so much thicker than fuzzi bunz. They squeek when she moves! It just feels so yucky and thick. She is in size large (around 22-23 lbs) and they just look so big on her! The Fuzzi Bunz she is on the tightest setting but they fit nice and trim. With the Happy heinys she has ant butt, it you can picture what I mean, this big bulky thing sticking out the back. I have 1 apron strings that fits nice and trim too. I thought everyone like the happy heinys better?
