Microfibre isn't to be used against the skin, its what the inserts in say, bumgenius pockets are made out of. You would never put it against the skin of a bub directly, its far too drying and god, I don't even like touching it with my fingers!!!

Microfleece is what is on the top layer of say, Haute pockets (bumgenius are suedecloth) and most WAHM's use microfleece as well - unless you request something like bamboo specifically.

We get rashes from suedecloth but not microfleece if that helps.
