Red onesie union suit has funny butt flap with a NO ENTRY sign screen printed on the flap. These onesies can be worn as pajamas or loungewear. Men or women can also wear these as one piece long john underwear or thermal underwear. Lighter than the original wool union suits, these jersey cotton onesies are more like your favorite t-shirt, but (no pun) they still have the convenient drop seat, also referred to as butt-flap, bum-flap, access hatch, fireman's flap and trap door.
