Since you're looking at this copy chances are you like the look of the Giro Bad Lieutenant Audio Helmet. It's not for everyone but it's a look that's quite popular. Better yet it does a great job of protecting that on-board computer between your ears and lets you pipe in your favorite tunes from your portable music device. Shrouded in a strong ABS shell a highly impact absorbent and lightweight EPS foam liner surrounds the skull in a safety certified barrier of protection. It's not ventilated but Super Fit™ sizing offers a snug feel that's comfortable throughout the day. The TuneUps™ audio system snaps into your portable music device without the use of tools and doesn't compromise the fit of the Bad Lieutenant one bit. In fact the earpads (which serve as the speakers) can be quickly removed if you prefer enhanced ventilation to music during warm late season days.
