About this item ERSEY KNIT 100% COTTON – Soft and lightweight 100% cotton, a natural breathable fiber that wicks away moisture and stays cool against the skin. This makes these onesie pajamas with feet perfect for year around sleep and lounge comfort. CLASSIC DESIGN WITH BETTER FABRICS – Styled like the original long johns, union suits and kid’s footie pajamas from earlier centuries, but not with the heavy wool fabrics. Our cotton jersey knit is soft, smooth, lightweight and stretchable; making these onesie footed pajamas as comfy as your favorite T-shirt. ADULT ONESIE FOOTED PAJAMA WITH A DROP SEAT FEATURES – Our jersey cotton footie onesies have an EZ snap front closure. Pajamas
