Two Hallucigenia sparsa glow white on blue like an Anna Atkins cyanotype: one in side view gripping a branching sponge and one from above resting in a soft tuft of filaments, with a second sponge and a small jellyfish drifting overhead. Hallucigenia was a spiny, legged worm from the Burgess Shale of British Columbia, about 505 million years ago, so strange it was first reconstructed upside down. One off-white ink on Navy, Black, Dark Chocolate, Dark Heather, Military Green or Tropical Blue. Made from lightweight 100% ring-spun cotton with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
