A laundry stuff pack should mean finally getting those two or three pairs of underwear that men have (and a few more for women) into the washer for that fresh bun smell but then again no new underwear...
I agree that the choice of underwear is little. Some new boxers for males and some new bras and undies for females would be nice. Also, I think kids could use some Voidcritter undies and tanktops.
