Made from 100% polyester, these Batman fleece lounge pants for men feature Batman's trademark Comic Book black bat and yellow circle symbol as well as the classic logo in an all-over print on  warm and cozy black fleece fabric lounge pants. These fleece pants are machine washable, have a button fly, a covered elastic waistband with drawstring tie. Batman is a huge fan of the fleece pants.  HUGE fan.  I think he may have been wearing them at last weeks' Justice League meeting.  Something about a state of prolonged,  Zen sleep...and Alfred not checking him over before he hopped in the teleporter.
