When people think of classic vintage toys, they think of the Rock 'Em Sock 'Em Robots! Made to look like two fighters, these robots were a classic trademark of the toy industry and continue to be used today! These pants have the classic Rock 'Em Sock 'Em Robots logo running up the left leg. The pants themselves are made of a soft 60% cotton and 40% polyester fabric blend, for casual wear and lounging about! These are the best!
