(Bio)Diversity Tee

100% of profits go to the American Academy of Underwater Sciences (AAUS) to support their Diversity Scholarship.

Made in California from 100% ringspun organic cotton and screen printed using bio-based, renewable algae ink, providing a soft hand feel and excellent wash durability. At large-scale production, algae black pigments are carbon negative! Algae absorb atmospheric carbon dioxide and that carbon gets “locked” into the bio-based black pigment for over 100 years.

Global Organic Textile Standard (GOTS) Certified, the worldwide leading standard for organic textiles like cotton. GOTS certification ensures our cotton is pure and ethically sourced and is made without chemical pesticides, forced labor, child labor, or unfair wages.

Happiness Guaranteed

We stand behind every product we make. If you have a problem, we will solve it with the relentless determination of a salmon swimming upstream to spawn.

The AAUS Diversity Scholarship was created to address an important problem: that recreational scuba diving is a privileged sport. Training costs money, the gear is expensive, and getting to dive sites adds up. When an aspiring marine scientist needs to dive to do their work but can’t afford to get their Open Water Scuba Certification, it creates a barrier to entry that hurts us all. It steers talented up & coming researchers into other fields and reduces the diversity that is essential to solving the world’s hardest problems.

The scholarship is targeted to those from underrepresented groups in diving, based on personal background, as demonstrated by a variety of factors, including but not limited to, educational experience, socioeconomic background, cultural heritage, race and ethnicity, and geographic origin. It covers an open water scuba course including online modules, confined water dives, open water dives, gear rental for the course, processing fees, and personal mask, fins, and snorkel.

Best tee shirt ever!!!

Shirt fits comfortably and the design is beyond amazing. I love supporting BIPOC creators and organizations. Also the representation in the ocean and water community is a great start to helping POC feel included.
