SLAYER in 2008 joined forces with O'Neal USA, one of the leading manufacturers of motorcycle and BMX accessories, to produce a limited edition of SLAYER helmets that feature the band's distinguished and celebrated artwork.

The helmets launched under the name of RockHard, and were sold at all Cycle Gear locations and at finer motorcycle dealerships worldwide. In addition, each helmet was certified and numbered with its own Certificate Of Authenticity.

SLAYER's official webstore is now offering O'Neal RockHard Full Face helmets individually autographed by all four members of the band (Kerry King, Tom Araya, Jeff Hanneman and Dave Lombardo). Only 13 of these — priced at $499 apiece — are available.

RockHard Helmets has also produced limited-edition helmets for AC/DC, KISS and LYNYRD SKYNYRD, among others.

SLAYER are set to headline the second day of the LOUD FESTIVAL 2012 in Sofia on June 3.
