These two diapers were made with flannel as the outer layer and t-shirt as the inner layer as recommended in the pattern I used. The soaker in one is both flannel and t-shirt and in the other one it is all flannel. I don't like these as much as the first one. The flannel is heavy so the elastic on the legs doesn't stay as snug. It also takes an eternity to dry b/c it is so thick and heavy. The performance seems to be the same as the all t-shirt diaper though.
