The second collection in Billabong's collaboration with Metallica, "Metallica x AI Forever," honors late world champion surfer Andy Irons. "He was a rebel in a rebellious sport," says singer/guitarist James Hetfield in a promotional video for the capsule collection that dropped over the weekend. The latest collection includes t-shirts, fleece hoodies, jerseys, surf trunks, jackets and tank tops celebrating the long friendship between the group and late three-time world champion surfer Irons, who died at age 32 in Nov. 2010.
