Three mantled howler monkeys sit in a row on a mossy rainforest branch, heads back and mouths wide, howling at a full moon that glows out of the dark shirt. The 90s howling-wolf tee, redone in airbrushed detail: gold rim light on black fur, the golden flank fringe that names the species, curled prehensile tails, jungle leaves and ALOUATTA PALLIATA in fine capitals. An enlarged hyoid bone makes howlers among the loudest land animals, though real troops mostly howl at dawn and dusk. Made from lightweight 100% ring-spun cotton with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
