Shark ID Tee

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.

A must have for all the shark lovers around the globe. A perfect tshirt to begin a conversation about these beautiful and complex creatures that have been so misunderstood for so long. Time to change the way people think of them! What a better way than wearing an ID shirt with the most iconic ones! Love mine so much.

Very nice

I bought this for my shark loving grandson. The sizing looks good, I got a 2XL. The fabric is beautiful, smooth and soft. I really like the greyish blue color. Maybe several more will be purchased.
