i think Monkey doodles use MICRO FLEECE as their staydry inner layer.

Greenkids and bum genius use SUEDECLOTH as their staydry inner layer.

my child started reacting to both microfleece and suedecloth, so i switched to natural fibre inners e.g bamboo velour, cotton velour, flannelette, sherpa, bamboo, hemp.

and the MCN i kept that has the inners she reacts to, i just use them sparingly, with a cotton velour double layer homesewn liner, lying inside them.
