Get your child supercharged with super powers from Asgard! The kids light up Thor costume includes a jumpsuit of dark gray 100% polyester interlock knit that has an elastic back waistband and Velcro tabs at center back. It has soft-sculpted fiberfill padding on the chest & shoulders to give a muscular look. Thor's armor is printed on the chest, arms and legs, including large circular plates in front and printed mail along the arms, and red stripes down the side seams. A polyfoam Belt of Strength is attached to the waist of the jumpsuit. The knee-length red cape attaches to the shoulders of the jumpsuit with Velcro strips and has foam shoulder pads to enhance the muscular look. A rivet on the front of each shoulder is outlined with LED lights that blink when turned on. The battery pack with the on/off switch fits into a pocket on the inside of the suit, and uses two AG13-LR44 hearing-aid-type batteries. Batteries are included, but we recommend purchasing extras. Team this little superhero with Captain America and the Hulk to assemble the Avengers.
