They don't call Captain America the First Avenger for nothing. This guy fought in World War I, and took part in a Super Soldier program that transformed him into the superhero Marvel fans know and love. You probably guessed that this would make him pretty old, but the hero didn't age when he was frozen in Alaska. With the Classic Captain America Boys' Avengers Costume, your son can become the Avengers' iconic leader this Halloween. This costume features a red white and blue jumpsuit, and a blue headpiece. Cap's shield is sold separately, and while it may not be indestructible, it is a great looking replica piece that will bring the costume together in a big way. If his friends dress as the rest of the Avengers, then he'll have a super powered group costume that will kick butt at their next Halloween party.
