You and a loved one can match in your colorful footie pajamas with bum flap, or select a festive pair that has a whimsical sign on the derriere. For instance, walk into a room with a construction-style sign on your bum that reads “Danger – Blasting Area – Keep Clear” and get ready for the laughter. A Velcro closure ensures that your footie pajamas for adults with butt flap will stay in place and secure.

Sizes range from XS to XXL for any body shape. Union-suit onesies for adults with bum flap can also be worn as thermal underwear and are made of 100% jersey-knit cotton. These are great for keeping warm while ice-skating or participating in other outdoor activities. Give a gift of adult drop-seat pajamas, and watch how soon these jammies turn into favorite sleeping attire.
