Part of O’Neal’s new RockHard line of helmets, the limited-edition Slayer model is as loud as the band it’s named after. The design will be available in full-face, half-shell and off-road helmets, and delivered in a box designed to look like the Anvil road cases the members of Slayer take on tour with them. The helmets, starting at $349, will go on sale February 25. We’re all about loud music and bikes, but we wish the designers had toned down the use of logos. Other editions in the line will include KISS, AC/DC and a Hustler model, which is every bit as trashy as it sounds.
