The urban sleep suit was designed by Forrest Jessee for the bustling non-stop lifestyle of contemporary cosmopolitans.   The urban sleep suit is a take-anywhere, nap-anytime ensemble made to be slept in on the spot.  Buckminster Fuller could have really used one of these outfits.  Did you know he was a proponent of polyphasic sleep, taking just four thirty-minute naps a day for nearly two years?
