These doublers are 3 layers of thick lofty microfiber or 3 layers of wonderful organic Bamboo fleece.

The Microfiber doublers have a top layer of smooth soft fleece for a stay dry affect for baby.

Both very absorbent, yet very trim for older babies, heavy wetters or nap/nightime.

If your baby is over 3 months old, doublers are a good idea. Also, if your baby is a heavy wetter, please try using 2 doublers!

They work great, and the bamboo doublers are SUPER trim!
