My replica of a Spartan's helmet from Halo. Battle damaged touches, working LEDs and two little fans inside to keep meh coooool. It's largely fiberglass. Visor is also fog-up proof. I have the entire suit but I don't feel like getting all suited up just yet lol. With all of the modifications made, it costed me close to a thousand bucks for it all. ...Don't you love how I blow my money?
