The BIG FEET PAJAMA CO. Red Union Suit is a 100% cotton jersey knit onesie pajama built for year-round wear. Style 354-BLST comes in sizes XS through XXL in a classic union suit silhouette with a henley-style neck, long sleeves, and ankle-length coverage without attached feet. The cotton jersey knit is lightweight, breathable, and stretchable, wicking moisture and staying comfortable against the skin through every season. Flatlock seams run throughout the garment to prevent irritation, and tagless labels keep the neckline smooth while the rib-knit collar and sleeve ends hold their shape. The front features an EZ snap opening for easy on and off, while the rear drop seat opens independently so the onesie body stays in place. That drop seat is printed with DANGER BLASTING AREA, making this red onesie pajama one of the most recognized funny onesies for men and women at pajama parties, pub crawls, 5K runs, and holiday gatherings. Shoppers looking for a funny onesie, a butt flap onesie, or red onesie pajamas for a group event will find this union suit with flap fits the bill. The smooth cotton surface accepts screenprinting and iron-on heat transfers for custom group looks. Unisex sizing makes this onesie for men and womens onesie with flap an equally strong pick for couple onesies, college students, and anyone searching for funny pajamas for men, a mens union suit, or matching funny couples pajamas. Sold as a single-piece garment by BIG FEET PAJAMA CO., style 354-BLST.
