This vintage, retro engraving-style design features a Megatherium-inspired ground sloth with whimsical fairy wings and the phrase “I am extremely grounded,” illustrated in black and gray on a white shirt. Ground sloths were prominent during the Pleistocene Epoch of the Quaternary Period, combining accurate prehistoric mammal anatomy with playful natural history humor. 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.
