Superman is one of the founding members of the superhero team, The Justice League, known for being faster than a speeding bullet, more powerful than a locomotive, and The Man of Steel. The adopted son of Martha and Jonathan Kent, he goes by Clark Kent in his civilian free time and is a reporter at the 'Daily Planet,' where he can often be found spending time with Lois Lane. These pajama pants feature Superman's 'S' logo with the title words "The Man Of Steel" running down the pant leg. The pants themselves are made of a soft 60% cotton and 40% polyester fabric blend, perfect for casual wear and lounging about!
