This vintage-inspired natural history design features a whimsical bunny warrior riding a Dimetrodon, the iconic sail-backed synapsid from the Early Permian period. The black-and-white illustration style gives the shirt a retro, distressed scientific sketch aesthetic, combining paleontology artwork with playful fantasy elements on a clean white background. 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.
