I've seen Bamboobies mentioned several times -- are those the only ones you guys have experience with?
I've been using some wool ones that I ordered from Etsy. I like them unless I leak a lot, then they take forever to dry and the milk makes them hard. Wool, obviously, is a pain to wash compared to cotton/bamboo/etc.
I'd also like some that don't show so obviously under clothing (unlike my bulky wool ones).
