Celebrate one of nature's most fascinating nocturnal mammals with this vintage-inspired bat design featuring an adorable bat hanging upside down from a tree branch alongside the playful phrase "just hangin." Bats first evolved during the Eocene Epoch of the Paleogene Period, and this distressed-style illustration pays tribute to their unique lifestyle with a striking golden-yellow graphic printed on a deep navy blue shirt. 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.
