The tag on my LX zim pj does not indicate where it was made in, though I have trouble reading it.

I have a bought zim pj and I will compare, as soon as I can find it.

I heard that LH is a hard bargainer when it comes to caviar supply (LH offers a price that only Chinese producers can meet). It may be the same for LX's pjs. This being said, it is also a efficient way for Zimmerli to adverstise itself. Hence we cannot exclude that Zimmerli sells good quality products at a low price to LX. But it could also be the outlet product range, if Zimmerli has one. It would be interesting to know.

It is true that the words "specially designed for SWISS by Zimmerli" are suspicious.
