I flew back from BOS a week or so ago, and was offered the mens slippers, pyjamas, and washbag.
I declined and asked for the womens ones as I give them to the kids (giving a toddler something with a zip and things to open inside, is a fab game!).
I ended up with 2 sets of womens pyjamas, slippers & washbags, and one set of the mens pyjamas and washbag - very kind of the staff.
Crew were faultless throughout.
