Jenn "sand-papered the crap" out of an old helmet, painted it, added the extra bit, and added a ton of clear coating.
"Initially, it was the ugly duckling of helmets," Jenn told website Geekadelphia. "It looked pretty jacked up before I did my fairy godmother thing to it. It was an odd, dark maroon colour and it had been used as a rental helmet, so it had sustained damage over time. Long story short, I did a lot of spray painting and clear coating."

The helmet's even perfect for parties. It's probably perfect for just about anything.
