Edj,
I bought my boy's thermal suit from Mother Works @ great world city, the brand is Konfidence. At first I bought the smaller size which is up to 12 mths..but he can't fit on it, at the end I exchange to a bigger one up to 24 mths, a bit loose but more long lasting, price is $69, but I am a member so entitled to 10% disc. I think mothercare is also selling this brand if I'm not mistaken
