This vintage-inspired natural history design features a golden-brown woodland mouse surrounded by olive-green ferns, cream wildflowers, golden star accents, and red-orange fly agaric–style mushrooms on a deep navy shirt. The retro field-guide scene highlights Holocene and Quaternary woodland biodiversity, celebrating small mammals, fungi, and botanical meadow elements with a cozy nocturnal feel. Made from 100% ring-spun cotton (high-quality cotton) with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
