This vintage natural history design features a bushy-tailed woodrat (Neotoma cinerea) clutching a collection of bones, spiral shells, a pine cone, and other woodland treasures beneath the phrase “letting go is not in my nature.” Rendered in warm sepia-brown linework on a cream shirt, the engraved-style artwork celebrates this modern Holocene Epoch rodent’s well-documented collecting behavior. 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.
