Bamboo french terry, has a smooth jersey side (like a t shirt) and has a low terry side- not nubbly like a towel. Bamboo is my favorite fabric for soakers. Dries quickly and offers a great amount of absorbency with only a few layers. 3 layers is perfect for daytime soaker, and can be doubled up for night time use.
Bamboo works well for all in ones or pockets. Excellent for pull-ups, even for heavy bed wetters. The fabric stays soft and supple through many washes.
Fabric does shrink and should be washed and dried before cutting for use or you will end up with a small product. It does take dye well, my children wore pants and hoodies out of bamboo terry in many colors. I did machine dying, it took well without spots.
