Salomon Brigade Audio Helmet
Here's what other sites are saying:
Rolling deep in the park is the only way you know. It's time to add one more member to your crew, though: the Salomon Brigade Audio Helmet. Its injected ABS shell and EPS foam padding keep your melon from getting banged up on icy pipe walls and big ol' booters, and the Airflow Concept vents keep cool air flowing over your domepiece so you don't heat up like a pizza bagel in the microwave. Best of all, though, the Brigade has a built-in audio system, so you can just plug your tunes in and ride without having to fiddle with your earbuds.
