I love off the wall merchandise, but when it comes to Slayer merch this is a must have for any collector. 

Back in 2008 Slayer joined forces with O'Neal USA, one of the front runners for producing motorcycle and BMX accessories. And what was produced a killer Slayer motorcycle helmet that would please any Slayer fan.

Slayer's official website is now offering these helmets singed by all 4 members. But you better hurry and grab one up because only 13 will be made available, with a price price tag of just $499. When it comes to Slayer somethings just shouldn't have a price tag.

Check out these awesome helmets right here.
