The quality of the PJ's found on in F is not comparable to the ones for sale directly by the company, which are probably one of the best you will find worldwide, which also will explain the price. The PJ's of LX F are very good and comfortable, I actually use only these at home

but can't be compared to the "real" thing. LX used to have for a short while PJ's which were of a higher quality on the A340's as a compensation for the inferior product.
