Wear the Mastodon ADMAT T-Shirt — officially licensed Mastodon merchandise in black cotton, built around the Atlanta prog-metal band's signature ornate visual sensibility.

Mastodon (Brent Hinds, Bill Kelliher, Brann Dailor and Troy Sanders) have always paired their progressive sludge-metal songwriting with intricate illustrated cover art and merchandise design across Leviathan, Crack the Skye, The Hunter and beyond. The ADMAT design fits squarely into that tradition of layered, mythological visual ambition.

The unisex cut runs comfortable for gig nights and pit time. Cotton holds the print sharp wash after wash. Essential rotation for any Mastodon collector and prog-metal vinyl head.
