There are a lot of people over here (France) who will only use pockets etc. with natural inners - I hear a lot more about microfleece and suedecloth allergies/intolerances on the French forums than I ever have on UK forums. NO idea why that is
, maybe they're paranoid, or maybe they're more clued in to the possible causes of redness/reactions (i.e., and don't just think "my LO can't handle cloth")?
Personally I prefer a stay-dry inner but I'd have thought there was a market for natural inners too. Can't comment on the wicking issue, really - we didn't get on too well with Econappies (OCV inner) but that's the only one I've tried, and DD only wore them a few times.
Are these ones you're making or thinking of importing? I know Blueberry makes an OBV-lined version of their pockets now but don't think I've seen anyone in the UK selling them (they are on sale in France though!).
OBV is all the rage, I bet lots of people would at least want to try it as a pocket inner.
ETA: Oops, I've literally just this second found the bamboo BBs on sale in one shop, wasn't even looking for them...
