This retro, vintage-inspired design channels the richly illustrated look of a 1990s natural history textbook, depicting a lush freshwater ecosystem with a river otter, woodland birds, flowing water, ferns, mosses, wildflowers, and aquatic plants. Deep forest greens, earthy browns, muted blues, soft pinks, and cream highlights create a detailed, nostalgic field-guide aesthetic against the black 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.
