Wield the Mastodon T-Shirt: Leaf Beast in black soft-style cotton — officially licensed Mastodon merchandise, printed with the Leaf Beast creature graphic across the front.

The Leaf Beast design fits Mastodon's usual illustrative catalogue register: an intricate creature-and-foliage composition rendered as a single detailed front print. The kind of graphic that rewards a closer look.

Built on a unisex short-sleeve cotton body, black. The dense front-print detail holds the shirt on its own; works as a subtler catalogue piece than a wordmark-heavy tee.
