I've got one called Tirsokas. It's not BTP, but is the most amazingly slim nappy I've ever seen. It's got that breathable sports fabric inside instead of fleece, - I think it's called coolmax, and that's why it's so slim, and it dries so quickly it's amazing! I've got ellas house hemp inserts with it, which soak up loads without being bulky. It's a real show off nappy with hedgehogs on it!
