Top off with the Mastodon Baseball Cap: Logo in Sonic Silver or Black cotton — officially licensed Mastodon merchandise carrying the band's wordmark across the crown.

Troy Sanders, Brann Dailor, Brent Hinds and Bill Kelliher formed Mastodon in Atlanta in 2000 and built a progressive-metal register through Remission in 2002, Leviathan in 2004, Blood Mountain in 2006 and Crack the Skye in 2009. The wordmark holds the same conceptual weight as the sleeve arc.

The Sonic Silver crown reads metallic across the panel; the Black cotton crown carries the Sonic Silver treatment applied to a matte base. Adjustable rear strap sets the fit.
