Our "Santa's Lil' Helper" PJ sold out last year, so we are bringing it back and adding more styles and colors. This is the best PJ on the market today. It features super soft 100% thermal cotton. The PJ has fantastic stretch which makes it very comfortable to wear and easy top put on. We embroidered the bottom with "Santa's Lil' Helper." It also features an open tail end for quick potty breaks.
