Not only have I heard of them, I have some of them. My MIL used them on my husband and BIN and they were in great shape so I used them on my son. They held up great. She also used a cloth diaper labeled "Dexter Diaper" from the Dexter Diaper Factory in Houston, Texas which is no longer there. Both worked great, but the Dexter diaper didn't have closures. You could use inserts in either diaper. If anyone is interested, I am willing to part with mine. They are still in great shape.
