This is a total of 8 helmets and vests. What spaced themed birthday can do without actual Astronauts! The kids will have so much fun. Keep in mind we have the "Space Ship" tent that is lined with photo panels that make you feel like you are on a spaceship! Couple that with the "Astonaut" combo unit and you can play in the entire galaxy! This is a must have for space themed parties. These helmets and vests are brand new and you will get to keep them after the party is over!
