Arguably the most colorful animals in the ocean, Nudibranchs come in thousands of different flavors. Our design celebrates this incredible diversity by combining 22 different species in a magnificent mosaic of sea slug splendor. 5% of sales will be donated to the Gosliner Slug Lab at the California Academy of Sciences, the world’s leading nudibranch research group that has discovered over 1500 new species.
Our signature fabric is sleek, soft, and luxurious, while strong, substantial, and resilient. It's got a gummy, supportive, and smoothing stretchiness you'll love, comfortably hugging you in all the right places.
88% Repreve® RPET (recycled polyester made from post-consumer plastic bottles), 12% spandex
Safe, premium performance yarns: Our high-quality, fully traceable yarns are sourced through sustainable partners in the U.S. These materials meet rigorous chemical safety standards and are independently verified for over 1,000 harmful substances like BPA and PFAS through OEKO-TEX® STANDARD 100 certification.
High-quality, responsible printing: Our products are printed using heat transfer sublimation, a printing technique that is widely considered to be the safest for both workers and the environment. It requires no water, eliminates dye from entering water systems, and minimizes ink and fabric waste. All the inks and dyes we use are also OEKO-TEX® STANDARD 100 certified.
Recycled materials, minimal waste: Our commitment to environmental responsibility starts with sustainable fibers and yarns. We use synthetic yarns made from recycled plastic bottles, which helps remove and repurpose existing plastic.

Nudibranchs are soft-bodied marine gastropod molluscs that come in a mind-boggling diversity of shapes and sizes. While the total number of species is unknown, scientists estimate there could be as many as 30,000. Only around 3,000 species have been formally described in the scientific literature so far, meaning there is a lot of work to do!
Besides being beautifully colored ocean ambassadors that inspire people around the world to champion ocean conservation, nudis are also ecologically significant members of the marine environment. They consume a diverse menu of prey, fill specific ecological niches, and have evolved incredible survival strategies that have been used to advance other fields, including biomedical research.
The Gosliner Slug Lab in the Invertebrate Zoology and Geology department at the California Academy of Sciences is the world’s leading research group studying nudibranchs globally. Led by the “Godfather of Nudibranchs,” Dr. Terry Gosliner, he and his team have identified and scientifically described over a third of known species. 5% of sales from your purchase will support research projects that include developing molecular methods to understand the diversity of nudibranch families and how nudibranch diversity can serve as indicators of ecosystem health and provide the basis for establishing new marine protected areas.
