The PJ's are fine. Lately they have been of a very heavy oxford cloth type material. Top and bottom. Look and feel brand new unlike the cardigan's. For all I know they may be new. Didn't notice anything "used" about them. If you don't have trouble putting on a hotel bathrobe in your room you will not have an issue witht the PJ's. They are passed out in sealed plastic bags. Make sure to ask for an LL size you you are larger than the average Japanese. They are available but I always need to ask as only L's are placed in your seat prior to boarding.
