“Beautiful tee, and love that it’s biodegradable and proceeds support the NMSF. The sizing is different from other all-gender tees, and it may because of this new innovative material. It’s a little boxy and more oversized than I expected. The shirt itself is also very thin.”
UBB x NMSF Collaboration Shirt
20% of sales from this shirt will directly benefit the National Marine Sanctuary Foundation, a leading voice for U.S. protected waters. NMSF works with communities to conserve and expand protections for healthy oceans, coasts, and the Great Lakes. Through the support of this collaboration, the National Marine Sanctuary Foundation aims to restore and protect the biodiversity and heritage within our waters as well as inspire a proud community of stewards to help conserve our ocean, coasts, and Great Lakes.
Eco-Friendly Innovation: Our tee is crafted from advanced biodegradable fibers made from recycled plastics that cause the rPET material to mimic the natural breakdown process of materials like wool. These fibers break down by 90% in 3 years when exposed to specific landfill environments, minimizing the impact that traditional rPET materials have on the environment through micro-plastic pollution and the inability to be recycled..
Better for the Planet: Our new cutting-edge biodegradable fibers, treated with Ciclo™, offer a more sustainable alternative, reducing the environmental impact of microplastics and helping to protect our planet for future generations.
Don't worry. They will NOT break down by washing them.
Why You'll Love It:
Feel Good, Look Good, Do Good: Wear your values with pride. By choosing the "Protect Our Waters" tee, you're supporting debris removal efforts as well as water conservation.

"I bought this for my 65 year old , a bit overweight husband. The design is nice and the cause wonderful and much appreciated. This thin of a T-shirt tho is made for a younger and / or thinner person. It shows every bulge and is not flattering. Good sleep shirt for me perhaps ?"
