Suit up in the Mastodon T-Shirt: Seated Sovereign in black soft-style cotton — officially licensed Mastodon merchandise wearing Atlanta's progressive-metal heavyweights in throne-and-crown form.

Mastodon emerged out of Atlanta in 2000 around Brann Dailor, Brent Hinds, Bill Kelliher and Troy Sanders, building a singular progressive-sludge-metal catalogue across Remission, Leviathan, Blood Mountain, Crack the Skye, The Hunter, Once More 'Round the Sun, Emperor of Sand and Hushed and Grim. The Seated Sovereign design pulls from Mastodon's appetite for mythological-and-throne imagery that runs across their album-art history.

Available in a black colourway, the unisex cut runs straight through the body in soft-style cotton, ready for daily wear.
