I have 3! I like them. They are a cotton AI2 so they are a little prone to wicking but only when I have left them on for a bit too long. They have a snap in booster which I think is 2 or 3 layers of bamboo then a bio fold lay in.
The lady who makes them is great on customer service. I bought one when she had her blog set up for her first sales & it wasn't the best fit on Iain at the time as he was a little younger then her tester range (3 months at the time) so she made me another slightly smaller to fit him till the other fit him free of charge! I recently got one with a matching singlet. Its so cute Login | Facebook its on face book so not sure if you can see it without adding me.
