I use GreenKids - love them! They're lined with microfleece so bub doesn't feel the wetness.
I just wanted to point out that Green Kids are lined with suedecloth - not microfleece

Once you go to the dark side SJ - you'll never go back.

Sami - you can use the Ecobubs over night - I think you would be fine teaming it with their microfibre insert and a green kids bamboo insert. I use that during the day for DS, but I'm sure I could get away with it at night too. Plus you'll have the protection of a wool cover - and no need to lanolise - bonus!!
