The Adult Footie Pajamas with the red and black plaid print are a true classic. They are made of 100% cotton flannel and are double-brushed for added softness and comfort. These pajamas button up the front and have non-slip soles. The yarn-dyed woven plaids make the onesie as soft and comfortable as possible while also making the ideal winter-wear outfit. Perfect for both men and women, the Adult Footie Pajamas are an excellent time machine that take you right back to your childhood.
